Leaves hair soft and thick. Both shampoo and conditioner add fullness and body

I buy it because it is sulfate free and it smells great.

Some recommend this shampoo because I was loosing too much hair. I just started using it hopefully it works. It smells great and I love how my hair feels.

I have an allergy using some hair shampoos, but not with the Biotin & Collagen. That is why I tried B&C. I like what it does with my hair and have no itchy scalp afterwards.

The new OGX Biotin & Collagen shampoo formula is not working for my hair. Please bring back the original formula — it had the perfect texture, fragrance, and effect.

The shampoo does its job of making my hair feel clean and manageable, but it’s too strongly scented for me. I don’t have allergies to perfumes, but would recommend that anyone who does should be cautious about trying this.

Love, love, love this shampoo. I can't say enough positive things about it! I highly recommend this for anyone that wants to keep their hair beautiful & lush!

They have removed sulphates, yet still have SILICONES? Not good because silicones will clog your hair follicles and eventually you will have hairloss. It might be noticeable in a few days, a few weeks, a few months, or even in a year or more --- but it will happen. It happened to ke with these horrible non sulphate, silicone containing shampoos. It took me 3 years to get my thick hair back by going silicone free! Don't believe me? *shrugs* Chance it then and see what happens, but don't cry foul when you notice lots of hair in your shower drain. Don't blame it on stress, or hard water, or heat styling. It is the SILICONES in these shampoos! Shampoos are for cleansing the scalp and your hair. They are NOT for giving slip or conditioning! That is what conditioners are for! Sulphates do NOT cause hair fall. Use your heads. In the 70s, ALL shampoos contained sulphates and NONE had silicones, and we all had tons of hair! OILS are a healthy way to seal hair to keep it frizz fee. Try Abyssinian Oil, which is also a great heat protectant. If you do want to use these silicone shampoos, you better also use a sulphate shampoo every few washes to remove buildup. Ok. You have been warned, now make your own decision. As for me? I continue to ONLY seek out sulphate shampoos that are silicone free. Ones I love are Redken Extreme Length shampoo, Nexxus Keraphix shampoo, and Nexxus Therappe shampoo. Conditioners I use that are silicone FREE are Redken Extreme Length in the lighter aqua bottle. The darker one does contain silicone. DO nOT use any Nexxus conditioners other than Nexxus Clear, as the rest contain silicone. BIOLAGE Ultra Hydra Conditioner is GREAT and silicone free! Maui Shea Butter Mask is FABULOUS! Redken CAT spray protein is amazing and silicone free! And OLAPLEX no3 is also excellent. Good luck!

My 19 year old son used this and said it dried his hair out and I thought he was just being picky but after trying it for about a week, my scalp got dry and became itchy. I used the shampoo along with the conditioner. It was light but didn't like the drying.

I'm most impressed with this shampoo. I've been using it for a couple weeks. I don't think my hair has ever looked better. It smells good and makes my look shiny and healthy. I haven't noticed any frizzing even when it rained for over a week. I think it performs better than some of the other much more expensive shampoos. I will definitely purchase this product again.
