Old formula was changed to not so good new one
I've been using this for so many years but unfortunately the new formula which i've been using only for 1 week makes my hair dry, dull and unmanageable. Also, you need to use a lot since i am not sure if it's cleaning my hair properly, the texture of the product from milky rich to loose translucent. Hopefully, the company will bring back the old formula. It's sad to change from excellent quality to definitely not so good.

Not cleansing enough for my oily roots and too much to use daily. Smells wonderful though! I would reccomend to someone that has normal roots not super oily like mine.

And what I especially love is that, since my hair tends to get oily, it stays fresh and clean for longer after using it. That’s a big plus for me.
I’ve been using this shampoo for about two weeks, and I really love it! It gives my hair noticeably more volume and makes it feel fuller without weighing it down. The texture is pleasant, it lathers nicely, and my hair feels clean, soft, and fresh after washing. I also love that it’s sulfate-free. Overall, I’m very happy with the results and would definitely recommend this shampoo!

Lasting fullness, less hair falling out
My hair is fine and falling out. I have tried sulfate free Dove, L’Oréal, Native and several other brands. OXY is the only one that gives me true LASTING fullness with the least amount of hair falling out. I have been using it for 4 weeks now.

Worst shampoo
I bought last week and I found my hair become rough, lifeless after using this shampoo. I was so hopeful before using this shampoo but after a couple of uses I experienced that this is the worst shampoo I have used. Hair are so lifeless, rough and sticky. I am very much disappointed. Total waste of money.

This biotin shampoo leaves your hair soft, silky, and with a lovely scent.
This shampoo promotes hair growth, has a rich scent, and leaves your hair soft and silky. Apply it to your scalp and massage while washing. It also helps with dryness and split ends.

The effect is just wow!
Very high-quality and effective shampoo with a pleasant smell. I have very long and thick hair. And he helps me. The composition contains collagen. And it's very good for the hair.

SILICONE + NO SULPHATES = HAIRLOSS!
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!

This shampoo works!
This shampoo lathers up really nice and left my hair feeling clean and soft! The packaging is effective and easy to use. Sometimes I find the pumps on certain shampoos annoying but this one is nice. I noticed my hair with more of a shine after using only once!

Works wonders!
I have dry overprocessed hair because of bleaching, and am in my 50s. Not many products do what they say, but after using this shampoo, my hair is always silky soft. I love it! My hair is also curly so frizz is always an issue... But not with this shampoo. So if you have the same problems I do, then I encourage you to try it. You won't be disappointed!

Hair care
I have been using OGX Biotin & Collagen Shampoo. It gives my hair a fuller look. It's quite expensive but its worth it. The texture is thicker than regular shampoo, and the scent is mild.
