Growing up I had thick curly hair and after dying it several times and bleaching it a couple of times my hair lost a lot of its thickness and a lot of its curl. It started breaking at the ends and it became so thin it started scaring me. I've been using this shampoo and the conditioner that goes with it for a few weeks now and my hair is so much healthier already! I'm very excited to see the results after using this product for a few months. I've already started noticing my hair feeling thicker and my curls are coming back like they were before. This product is magical! And it smells great!

I decided to try ogx because I saw so many positive reviews for that brand on here. My hair definitely has more volume after use, although the conditioner doesn't leave my hair as smooth as other conditioners do. The scent is light, it smells kind of like coconut. The price was very reasonable, and I think it would work well for most hair types.

OGX Beauty Biotin and Collagen Shampoo is a hair care product formulated to strengthen and volumize hair. It typically contains biotin, a B vitamin known for promoting hair growth and health, and collagen, which helps improve hair's elasticity and thickness. This shampoo is designed to nourish and fortify hair strands, leaving them looking fuller and healthier. My hair is so smooth and firm when using it. Highly recommend!

While I never really noticed a difference in thickness while using this product which is why I gave it a 4 out of 5 stars. Ive noticed myself rebuying this product just because I how my hair looks and feels while using this shampoo. I will mention that I use both shampoo and conditioner.

I am a 64 year old female and have had "super" baby fine hair my entire life. I have tried many hair products throughout the years that claim to improve the look and texture of your hair but, this one is the ONLY one that has ever actually worked. After my very first shampoo, I noticed the difference, as did my husband. Very little of this product (a drop or two) is all that is needed for really great results. If you have baby fine hair, you should try this shampoo. You will not regret it!

Are you able to try this one time and I fell in love I highly recommend this product and would love to use it again unfortunately the price is just not in my range I have long thick hair and one bottle of this does not last me very long although the shampoo is well worth it I have to work in my budget.

This is my go to shampoo for flat straight hair. I’ve always had a problem with volume and oiliness and I feel like this shampoo doesn’t weigh me down at all and gives my hair a good amount of volume. I’ve used this religiously for a couple of years now.

[This review was collected as part of a promotion.] This shampoo was not bad. It's not my favorite but it's decent. It's smells clean and the bottle comes with a good amount for the price. I say it's not my favorite because it doesn't do much for my hair. My hair actually felt drier after use. It might be good for someone with oily hair.

If I were to compare this scent to a perfume, I would say it almost smells like Victorias Secret Love Spell- who doesnt love that scent??! But the formula works great on my 7 year old & me! She has LONG thick coarse hair like I do & this softens/lightens it so much. Making our normally damaging-looking hair SUPER soft & shiny! Love love love it! With the matching Conditioner as well of course!

[product:ogx-biotin-collagen-shampoo-385ml] This stuff is great and I always get the best results! Combined with the [product:ogx-biotin-collagen-conditioner] of course. I love the smell, and it gives my hair real volume in my otherwise very flat hair.
