Biosilk Therapy Shampoo and Conditioner Duo with Keratin, 25 oz

I love love love this shampoo and conditioner! I have really long hair. I don't use nearly as much product as I use to. I've been using Biosilk for about a year now. It smells super good and leaves my hair soft. I use all the hair products. They even have Biosilk for dogs ( I also LOVE) my go to for sure!

The perfect formula! My hair is so tangly when wet and somehow this product makes it bearable and silky soft when dry. It has an amazing smell which is one of my favorite things about it. You also get a good amount for a decent price! I would be devastated if they ever discontinued this product!

I got this November 19th, 2025. Totally love it! I had really dry hair and kept losing a lot of it. My hair still falls out some, but not like it used to. This really made it grow back again and softer too! Also last awhile. Cause I still have plenty left. Once it runs out, I'm going to order myself more. My hair has been smelling good too! Keriten is supposed to make hair soft and shiny.

Only takes a small amount-rinses well and my hair feels awesome. I have gray hair and it does not any brassiness

The only negative is that they used sticky gum to keep the 2 bottles together and you can't get it off. Therefore bottles are sticky!!

I love the way my hair felt after I used this shampoo and conditioner. So soft and pretty. I wish it had a better scent. It wasn't bad but not the best and it's a very light scent

I am loving the thick silky smooth texture of both shampoo and conditioner! It strengthens as it softens the hair while detangling all of my strands. The smell is clean and fresh! The size is excellent, the tops easily lock and unlock with just a twist to the right or left. Excellent product I recommend this product it is a professional product my beautician uses it! Try it out, you'll fall in love with it!

The only thing this shampoo %26 conditioner has going for it is the smell. It honestly reminds me of Tresemme knock off. It does not lather up good and I have to wash my hair twice. It does not do anything as far as making your hair more smooth. I honestly would not recommend.

I had bought this product for my hair, thinking that with everything it said about the product that it would be good on my hair. It has fried my hair. I am losing hair from this product. It has dried out my hair and damaged my hair I would not suggest ever buy this product for your hair. It is horrible.

I use Bio Silk all the time for the fragrance this stuff smells awful will never buy this again stick to the original scent I get migraines and I cannot use this stuff because of the smell had to give it away!!
