There's a reason our hair serum went viral on TikTok. It works.

*These testimonials are based on the experiences of a few actual customers, but individual results can and will vary.

After helping 100,000+ grow beautiful looking hair, we know first-hand. There are 3 core ingredients in our proprietary formula for hair growth. 


Stimulates keratin production in hair follicles

Pea Sprout Extract

Pro-Vitamin B5

Helps add volume & sheen to your hair

Did you know using the wrong hair products can make hair growth even harder?

Thinning hair, breakage, and slow growth can result from many lifestyle factors or natural makeup of your hair.  It can also stem from using the wrong hair products.

Pureauty Naturals' biotin serum arms you with topical delivery of essential vitamins and minerals to nourish your hair and support fuller, thicker looking hair.

Here’s what you DON’T want in your Biotin Serum

Unfortunately, it's what you'll find in other products...

Junk filler ingredients

It's common for other hair care brands to load up on fillers to make it seem like you're getting a lot of product, when in actuality there are few active ingredients.

Beauty shouldn't be imported

Stay away from cheap beauty products! They’re manufacturing products in other countries to save costs. That savings can result in products that damage your hair & skin.

Others test on animals, we don't!

At Pureauty, we love animals. As pet owners, we can't imagine using a product that was ever tested on animals. That's why Pureauty products are never tested on animals.

Avoid brand new pop-up products

Don't be the guinea pig yourself! Pureauty Naturals has been the authority in Biotin hair care for years with hundreds of thousands of customers.

First time user

I almost gave up when I decided i will try one more bottle of the serum. Finishing up my 2nd bottle i begin to see my edges finally coming back after trying so many products. I am so excited and very pleased. I now use it all over my head and i am very excited about my journey with the biotin serum. They sent me a free bottle of biotin shampoo and I can't wait to try it. This stuff really works. HAPPY CUSTOMER

Hair serum

Of all the products I have purchased this has to be the worse one. It states that it thicken hair but the only thing it does with my hair is thins it out and lays completely flat. I have very thin and fine hair and was desperate for something to help make it fill fuller and thicker and I have tried this on several occasions with the exact same results. I still have all packaging and happy to send back at my expenses if you will refund my purchase price.

Smells and feels great!

I love this serum for maintaining a healthy scalp and hair! It's not oily, so I can use it anytime without worrying about when I'll be able to wash it out (unlike some oils). It smells great and the peppermint oil makes it perfectly tingly!

It works

Even my hairdresser was surprised. I am on the second bottle and the bold spot on the top of my head is gone.
