It’s time to review Pure Biology shampoo – because it’s a really popular product on Amazon.
So is this shampoo any good?
At first sight – it looks quite promising actually:
- quality ingredients
- many satisfied customers
- decent price
So is this product as great as it seems?
I tested it out myself so I can give you all the details I noticed.
Note: This review is based on my own experience + research on Pure Biology.
So Let’s Get To The Review
Full Name: Reviva Hair Shampoo from Pure Biology
Sizes: Only one (8 oz bottle)
Best Actual Price: Around $28
Cheapest Place To Buy: Probably Amazon
Designed For: It has 2 major purposes:
- Stimulating hair growth
- Decreasing hair loss
It also claims to fight thinning, breakage and DHT excess.
My Rating: 7 out of 10
Worth Buying?: It pretty much depends.
It’s not a bad product at all – but in my case, it didn’t work too well:
- mostly helped with hair loss (only partially)
- no effect for volume/thinning/growth
- needs to be used daily at first
If you want to see real effects, I recommend a cheaper shampoo that worked a lot better for me.
What I Liked About It
- Formula is pretty strong
- Contains 2 trademark ingredients
- Great citrus smell
- Improved my hair loss in about 2 months (just partially)
- Price is quite affordable (though not very cheap)
- Many satisfied users
- Available in several retailers
What I Didn’t Like About It
- You have to use it everyday on wet hair (in the first months)
- Made my hair loss worse in the first weeks
- Many complaints about side effects
- Didn’t increase my growth speed
- Effect doesn’t appear very fast (compared to supplements)
- No discounts for buying more bottles at once
#1 – Ingredients (9 out of 10)
This Reviva shampoo has a pretty good formula overall:
- based on 2 unique substances
- quality compounds
- all ingredients are disclosed
Compared to most shampoos on the market – Reviva is clearly superior.
It doesn’t have the very best formula, though.
Now – I would divide Reviva’s active ingredients in 2 groups:
- Proprietary Complexes
- Herbal Extracts
So let’s take a closer look at each by turn.
1. Proprietary Complexes
These are the 2 main ingredients from Reviva:
First of all – the 3HC Hair Stimulation Complex:
- it’s a blend from several plants
- stimulates follicles and stem cell proliferation 
- increases follicle lifespan
- decreases and prevents hair loss
Regarding the second complex (Amino Kera NPNF):
- designed for extra strength (immediate + long term)
- decreases general breakage
- penetrates better than other forms of keratin
Basically – these 2 ingredients are the main responsible for Reviva’s effect.
2. Herbal Extracts
These shampoo contains several herbal extracts – however:
- they come in very low dosages
- some don’t have any active effect for hair
Basically – these ingredients don’t help significantly (unlike the 2 complexes).
But here are the most important ones:
- Coconut Oil – moisturizes and hydrates hair strands. 
- Green Tea – blocks DHT excess and prevents shedding. 
- Rosemary Oil – nourishes roots and ends.
- Saw Palmetto – it’s the strongest DHT blocker among herbs.
Reviva has a pretty good formula (but mostly due to its 2 proprietary complexes):
- quality compounds
- several herbal extracts
- ingredients with clinical evidence behind
Just like many topical products – most compounds have no active effect.
But due to its 2 complexes – Reviva remains a good product overall.
#2 – Smell & Texture (10 out of 10)
Pure Biology’s shampoo looks great in terms of consistency.
This smell is actually one of my favorites (among all shampoos I tried):
- feels like a mix of lemon, orange and other citrus
- extremely refreshing (not sweet)
- average intensity
As I’m a fan of citrus scents – I personally love Revita’s fragrance.
If you prefer sweeter scents, this one is too fresh for your tastes.
When it comes to consistency – this shampoo isn’t too bad either:
- white to beige color
- lathers normally
- you don’t need a higher quantity than in other shampoos
- a bottle lasts more than 1 month (in my case)
Basically – it’s not the kind of shampoo that requires you to use a double amount to get the same foam.
So in terms of consistency, I can’t criticize it at all.
#3 – How To Use It (8 out of 10)
As every trustworthy brand – Pure Biology offers clear instructions about their product.
Here’s what the label recommends:
- Use it as a regular shampoo.
- Only apply it on wet hair and massage with your fingers.
- Let it sit for 30-60 seconds.
- Rinse normally afterwards.
But here comes the nasty part.
In the first months, it’s recommended to use the shampoo daily (for best results).
According to the label:
- you should see results in 2-3 months
- but only if you use it daily
- otherwise, it will probably take longer
Now – I personally don’t have enough time to wash and dry my hair daily.
So if I only used this product every 2-3 days, I would probably need (at least) 4 months to see any change.
Honestly – I couldn’t wait so much. And so couldn’t most of you.
That’s why this daily schedule is a major drawback about Reviva shampoo, if you ask me.
#4 – My Results (6 out of 10)
Reviva is one of the shampoos I tried in reality – and I wasn’t too impressed.
But I will try to give you more details about my hair problems.
1. My Background
As I said in other reviews – I used to deal with a serious hair loss:
- I was losing lots of hairs daily (for several years)
- my ends had thinned a lot
- the roots still had enough volume, but hair looked thin overall
- it was also growing very slow
I started with different shampoos and switched to supplements afterwards (they were far more effective).
So while I was trying out different shampoos – I also came across Reviva.
Since it had many reviews on Amazon, I wanted to give it a try.
2. How It Worked
First of all – I wasn’t very satisfied with this shampoo.
It’s true that I only used one bottle (for about 2 months). So my results aren’t 100% fair.
Anyway – here’s how it worked for me in those 2 months:
- My hair loss seemed to worsen in the first weeks.
- However, it got better in the second month.
- By the end of the bottle, I was losing about 40% less hairs.
- In terms of volume and thickness, I saw no difference.
- Hair didn’t seem to grow faster either.
- At times, it felt more brittle and dry than usual.
So overall – Reviva did improve my hair loss in the end.
If I had continued to use it, it might have helped more – but I can’t really tell.
Since it dried out my hair quite a lot, I decided to give it up and switch to something else.
Plus – I wasn’t extremely satisfied with my results that far.
That’s why I didn’t buy another bottle to continue the treatment.
Pure Biology’s shampoo did work in my case – so it’s surely not a scam.
But I did not see the excellent results I had been hoping for:
- only decreased my hair loss partially
- no change in growth/thinning
- hair felt a lot drier overall
Now – I might not be the most relevant case.
But in my opinion, Reviva isn’t the best choice ever (even though it does work).
I personally had some better results with another shampo.
#5 – Other Opinions (7 out of 10)
Just like I said before – my results with Reviva weren’t completely relevant.
That’s because I only used the shampoo for 2 months (which isn’t long enough).
For this reason – I tried to look for other users’ opinions.
Note: I only considered authentic reviews, not promotional ones.
1. What People Say
I mostly checked the reviews from Amazon – as they are 100% real.
Pure Biology’s shampoo has 4 stars out of 5 (from 1211 reviews).
These numbers are pretty good – to be honest.
So here’s what most people say about it:
- Some claim it’s really effective against hair loss.
- Others say it hydrates hair quite well.
- A few others claim it really helped their hair grow.
- Others say it’s effective but expensive.
- There are also many who were not satisfied.
- Some say it only made their hair fall out worse.
- Others claim they experienced serious side effects.
- Plus, a few others claim it simply did not help at all.
But overall – there are more satisfied users than unsatisfied ones.
So Reviva is clearly not a scam, since it works for so many people.
However, there’s quite a big negative side.
2. Biggest Complaints
Most unsatisfied users complain about:
- Worsened hair loss
- Side effects (irritation, rashes, scalp burns)
- No change after several months
- Hard to use (daily)
- Expensive for its real value
Now – I cannot say I agree with all these claims.
However, I also experiences worsened hair loss in the first months.
So other people might have experienced it for a longer period (which is surely not normal).
That’s why I’m convinced these complaints are real – as Reviva is far from perfect.
This shampoo has enough satisfied customers, overall.
However – it also has enough complaints.
So even though some have great results – others can experience a worsened shedding (as I did at first).
Therefore, I can’t guarantee this product is right for you.
It wasn’t right for me – that’s for sure. So it’s your own choice.
#6 – Price (7 out of 10)
Reviva has a good price overall – even though it’s not necessarily cheap.
Here’s what I mean.
1. The Exact Price
Pure Biology’s products are available on Amazon.
In fact – they have the lowest prices on this retailer. Regarding the Reviva shampoo:
- one bottle costs around $28
- it contains 8 oz (240 ml)
Now – this price is quite average.
It’s not very expensive, but it’s not too cheap either.
Still – in my opinion, Reviva is quite accessible even at this price.
If you don’t use it daily, one bottle may last even 2 months (as in my case).
However – in this situation, you will need a lot more time to see an effect. So it’s about the same thing in the end.
2. Competitors’ Price
I will only compare Reviva with my #1 recommended shampoo (Valotin).
- Reviva costs $28 per 8 oz.
- Valotin costs $30 for a 12 oz bottle.
- However, Reviva doesn’t come with any discount for higher quantities.
- Valotin offers a discount for buying more bottles at once.
- In this way, you can get it for about $24 per bottle.
- Reviva’s price doesn’t get any lower if you buy more bottles at once.
Now – these 2 products are both effective.
But I had much better results with Valotin’s shampoo.
Not to mention that it’s also cheaper (in terms of quantity) and more effective.
So I definitely recommend it instead.
Reviva isn’t very expensive overall. But it’s surely not the cheapest product ever.
So in terms of price – it’s both worth and not worth it:
- one bottle lasts more than 1 month (if you use it ever 2-3 days)
- costs more than most similar shampoos
Buts I said before – I personally recommend a cheaper alternative.
In terms of price – Reviva is quite decent. Not cheap or impressive, just decent.
#7 – Where To Find It (10 out of 10)
Reviva and all the other products from Pure Biology are pretty easy to find:
- available on retailers like Amazon, Ebay, etc.
- also available on the official website
Now – I would normally recommend buying Reviva from Pure Biology’s website.
However, prices tend to be higher there:
- an 8 oz bottle costs around $31 on PB’s website
- the same bottle costs around $28 on Amazon
- plus, Amazon also offers free shipping
So at this point – I would advise you to go for Amazon (for buying any of Pure Biology’s products).
Most are also available on Ebay.
However – buying them from Ebay isn’t as safe as Amazon, if you ask me.
So I would stick to Amazon at the moment.
#8 – FAQs
Coming up – I will try to answer the top questions about Reviva shampoo.
Note: I might repeat something I already mentioned, but it’s easier to spot here.
1. How long lasts one bottle?
The label doesn’t mention this.
However – in my case, it lasted about 2 months.
Just keep in mind that if you use it daily, it will probably last a lot less (1 month maybe).
2. How often should you use it?
According to the label:
- daily in the first months
- every 2-3 days afterwards
I personally did not follow this recommendation and I could still see a partial effect.
So if you can use it daily, I recommend doing so.
3. Can you use it with other drugs?
Certainly – there’s no risk of interactions between drugs/supplements and topical products.
4. Are there any side effects?
I personally experienced a worsened hair loss in the first weeks.
So this could be considered a side effect. Plus -I read several reviews complaining about:
- scalp irritations
- hair damage
But normally, these side effects are quite rare – so they surely don’t affect everyone.
5. How fast should you notice an improvement?
According to the label – it takes about 2-3 months for the shampoo to work.
However, this only happens if you use it daily.
If you use it more rarely, it’s probably going to take at least 4 months to see any change.
#9 – Final Conclusions
Here’s how I would sum up my opinion on Reviva shampoo (in 3 ideas).
1. Potent Formula
In terms of ingredients – this product looks pretty good:
- 2 trademark blends
- several herbal extracts
- varied ingredients overall
Now – those 2 proprietary blends are responsible for most of the effect.
But still, the formula looks better than in other shampoos.
2. Daily Use Required
According to the label:
- you have to use this shampoo daily (in the first months)
- afterwards, you can use it every 2-3 days
I personally could not use it so often – for one simple reasons.
You can only use it on wet hair, which means you have to wash your hair daily.
Unless you have a lot of free time, I doubt that’s very comfortable.
3. Takes Time To Work
Here’s how Revita works normally:
- typically, it takes about 2-3 months for it to work
- in my case, it took about 2 months to see an effect
- if you use it more rarely, it takes a lot more
So even if you used it daily – this product isn’t very fast.
However, if you used it as a regular shampoo (every 2-3 days), it would be extremely slow.
That’s why you should keep this in mind before buying it.
My Verdict – Is Reviva Shampoo Worth It?
Short answer: It depends.
It’s surely not a bad product – it works in many cases.
However, I personally would not buy or use it again – at least not when there are some many better options:
- Needs to be used daily in the first months.
- Effect appears quite slow.
- Doesn’t treat the actual cause of hair loss (from the inside).
- Not very effective for hair growth, thinning or volume (in my case).
- Side effects are more common than in other products.
As I said before, I’m not a big fan of this shampoo in general.
But if you really want a quality shampoo, I would recommend a product from Valotin.
Compared to Reviva, it has a better formula and overall effect.
It’s also cheaper and it comes in a higher quantity – so it’s totally worth it.
And I can speak from my own experience here.
