The smell is AMAZING! Makes my hair feel so soft and smooth! Adds awesome volume without drying out my scalp. I get so many compliments when I use this on how amazing my hair smells! This is definitely a monthly purchase!

I'm using this currently. It leaves my hair feeling moisturized and I guess volume is adequate. My scalp doesn't grease as quickly as it would with other products. Great scent. I'd say I'm satisfied and would recommend

This helps me get the hair I want. No dead lame solitaire hair. Your hair has added bounce and shine. Highlights in my hair shine more with this product actually my highlights are frosted so much shine and I think it's thanks to ogx. My kinda clean

I absolutely love the Ogx brand for their shampoos and conditioners! This specific duo of shampoo and conditioner I feel does it's job of strengthening and voluminizing hair with the biotin! I'm very satisfied with it.

This condition smells so amazing. I use it after a deep cleaning shampoo and it always leaves my hair so soft. Even my partner has noticed his hair getting thinker after using this.

I have been using the biotin collagen conditioner for 4 months now and it is my favorite hair conditioner. It has a nice smell and texture, it makes my hair soft and shiny, and I also like the ingredients.

I pair this with the shampoo and it keeps my hair feeling great. A great product for its price especially with how many uses you can get from bottle. The ends of my hair feel moisturized

I have always used OGX products since my aunt recommended it. With the biotin in the shampoo and conditioner has really made my hair full, healthy and gives my hair shine. And it smells good too.

While using in the shower, you can immediately feel that your hair is thicker and more full. U barely need to use any and the smell is wonderful. I used both the shampoo and conditioner but I believe the shampoo shows the most results

I really like the way this product worked. I got the sample size the 1st time to see it made my curls more bouncy so I then got the bigger bottle. I'm still looking for one with a pump just because pumps are easier in the shower. My opinion
