This is by far my favorite drug store shampoo! I love it! It makes my hair feel soft and smooth, and when my hair dries it looks silky and shiny, overall it makes my hair look so healthy! It has also helped me with hair growth! It's amazing! 10/10 I highly recommend it!

Leaves my hair feeling super clean. This is the only shampoo I have used that has not left my hair feeling super dry and weighed down. Not to mention it smells really good. I have been using this shampoo for almost 5-6 months. (Pics of curls on wash days)

The shampoo lathered up well but this was the worst shampoo I ever used. My hair thinned so bad I almost lost half pf my hair. I never correlated the hair loss to this shampoo because it was supposed to make it grow. I would never recommend this and never buy this. OGX Biotin & Collagen Shampoo

I used to have thick hair, but after highschool my hair started thinning and not growing as fast. So, I tried this and my friends have noticed my hair is thicker. I don't think it works as well as it's hyped up to be, but it still thickens my hair. I was expecting my hair to be as thick as it was in highschool, and it's not there yet. I'm almost done with my first (big) bottle of shampoo and conditioner, so maybe my hair will get even thicker and healthier the longer I use it.

I wanted to try to get my hair thicker and grow longer and I tried both the shampoo and conditioner and I like both of these. I “think” I've seen a difference in my hair. I can't lie though I like a silkier feel to my hair with conditioner. This leaves a tougher feel to my hair. I want more manageable hair but this is a very good product like I said I think I see a difference with my hair in length and thickness.

I love OGX because it washes well and it doesn't dry out my hair. This shampoo lathers very minimally but it's a good thing. I found that shampoos that lather too much dry and strip your hair of natural oils. The smell of this Biotin and Collagen is great! Your hair will feel healthy after using it. The product is thick and it your hair will smell and look great. I highly recommend OGX products.

First of all.... THE SMELL IS AMAZING! Its strong but I love it. This shampoo makes my hair feel clean and it stays cleaner before washing. My hair feels and looks healthy. I've been using this for 2 months and I have noticed a great difference. I will continue to try hair products from this brand!

Looking for beautiful, healthy-looking hair? It all starts with the right shampoo! I fell in love with OGX Thick&Full + BIOTIN & COLLAGEN SHAMPOO. I recommend to try this product if your scalp is very sensitive and you can't find the right shampoo for yourself. This shampoo takes care of your hair & scalp! It's great for you if you have such problems as hair loss, no volume, problems with hair growth and if you have very sensitive skin! After washing my hair, it looks very healthy, shiny, smells great, and the product adds some touchable softness and smoothness!

This conditioner has really helped my frizzy hair. It has conditioned and give my hair the boost of energy that it needs. I purposely was looking for a biotin product, but since I am still breastfeeding my daughter, I have to opt for non-consumables and this is not a downer.

I want to love this product more than I do, but it just didn't do the trick for me. I have fine hair and while it did help add volume to it after a few washes I noticed that it also sucked out the moisture from my hair. It's unfortunate because I did like the increased density, but don't anticipate me repurchasing this shampoo.
