This shampoo and conditioner together are a perfect match and very effective with continuous use with strengthing hair strands and with hair growth. The quality is is salon like and leaves your hair feeling smooth soft and silky. It smells amazing and super easy instructions for washing and rinsing I would recommend this 1 million times over.

A little backstory…I have really fine hair that is starting to thin around my hairline and has no volume unless I curl or back comb it. I'm really picky with hair products because of that plus I color my hair. I'm not joking when I say this, but I noticed a difference after the first time I used this. My hair had volume that actually lasted. I had lift at the roots and I noticed even more volume when I curled my hair. It didn't mess with my coloring either and has a nice scent. The second time I used it, I still had great results.

I have been using the OGX Biotin & Collagen Shampoo for a few weeks and the results are amazing. The texture is thick and luxurious, and it creates a rich lather that leaves my hair feeling super clean. Since I started using it with a regular frequency, I've noticed my hair looks much fuller and has a healthy shine. It really delivers on its promise of adding volume without weighing it down

I have fine, shoulder length hair with waves. This stuff cleans my hair without weighing it down, it doesn't create volume but it doesn't say it will. I also don't have much frizziness afterwards. Pleasant, light scent. A little goes a long way. Overall a good shampoo.

The OGX Thick & Full + Biotin & Collagen Volumizing shampoo works wonderfully! It leaves my hair feeling thicker, fuller, and healthier without weighing it down. After just a few uses, my hair looked more voluminous and had great bounce. It smells amazing, lathers well, and rinses clean without leaving residue. Perfect for fine or flat hair, and a little goes a long way. I'm very happy with the results— I will never use anything else!

This product, along with the conditioner is my absolute go to for my hair extensions. It keeps them feeling soft and moisturized. No stiffness, dryness or itchiness. Just light flowing hair. The scent is subtle but gorgeous too! It lathers really well and easy to dispense; a little goes a long way.

I have used OGX products for many years. They have a great variety and affordable. I like this particular option as it adds shine and softens to my hair. However, it could be a little heavy for some so switching up your hair care every so often helps with that.

I've been using the OGX biotin and collagen shampoo and impressed with the results. It leaves my hair feeling incredibly soft and manageable right after the first wash.it's leaves a subtle fragrance that you can actually notice every time you move your hair. If you're looking for hair growth and stretching, this it is ! Since I started using OGX my hair feels thicker and much sturdier.

Works better than I expected. My hair is noticably thicker. Smells good too.

Great Shampoo if you have fine hair, makes it fuller looking.
