I bought Organix's Thick and Full Biotin & Collagen shampoo to help me get thicker, fuller, and longer hair; and let me say it works 110%!!! My hair is full and voluminous, and since I have started using it my hair is now almost to my hips :) I would definitely suggest giving their Biotin & Collagen line a shot!

I switch it up between the OGX keratin shampoo/conditioner and the OGX biotin and collagen shampoo/conditioner. I saw amazing results with my hair almost instantly that I’ve stuck with this brand and these products now for a few years and I would never go back to any other drug store brand.

I have 3c/4a natural hair and I've stopped using shampoo about a year ago. But instead of picking up my cleansing cowash, I used biotin & collagen shampoo this morning. I must say this is by far THE BEST SHAMPOO I've ever used!!!! I only needed a small amount of this to saturate my entire scalp/hair. This shampoo almost worked as a detangler because it did not leave my hair "brittle" and "stiff" while washing. I would recommend

I am 45 years old. I have struggled with thyroid issues which has thinned my hair alot. I used this product years ago and had much success with fullness and growth. I am currently using it again and have seen the same results. I would definitely recommend this duo.

I love the biotin and collagen Ogx shampoo and conditioner. It has a great smell and it helps keep my hair strong and healthy. My hair had gotten a bit thinner so I figured I’d give this product a try and I love it. After a couple weeks I could already notice that my hair was feeling much more full and healthy like before.

I absolutely ADORE this product! Normally, my hair gets very frizzy and , although it is wavy/curly, it never had any sort of shape. However, once I started using this shampoo I noticed a DRASTIC change to the health of my hair! It is no longer frizzy and it actually has shape. I no longer need to apply heat to it! I hope they never discontinue this product!

I had purchased a box set of the OGX Biotin and Collagen shampoo and conditioner at an off priced store in MA and brought it to Fl where I used it in my outdoor shower. I live everything about it. Lathers great, smells great, conditioner leaves my hair tangle free. I have not found as good a deal but I recently purchased the coconut milk version shampoo and conditioner but have not yet tried it.

Do you have thin hair and want to change that? I have been using this for a year and I have definitely seen growth in my hair an the thickness of it! You can get this at your local store and adding the conditioner with it is amazing too. Smells great!!

I wanted a product that would help bring my brittle oily hair back to life. I saw this and though volume and vitamins great! At first I used it like normal shampoo and conditioner because the direction read like normal shampoo and conditioner. We'll it made my hair oily and limp and I was less than happy about it. There was no volume at all, and it literally looked greasy like I hadnt washed it in two days. I was just about to throw it away when I ranted about it on FB. A friend told me to try washing it twice and only conditioning the ends. I did this and have had wonderful results since. Washing it twice has really helped. I don't have the oily features or limpness anymore. Please give this product a chance and experiment to see what works best for you. This went for trash to treasure for me. Good luck!

I bought this a couple of times. I really enjoyed using it. I felt like I was doing something good for my hair when using it! I stopped buying because I’m pretty cheap when it comes to most things but I will buy again one day. It did give my hair more volume and it felt bouncy all day.
