Gives me super soft hair

I have really damaged year due to years of bleaching/coloring. I've tested other treatments/conditioners that promised the same results but were x3 more expensive, but this by far works the best for my hair. I have very thick wavy asian hair that turned into a hay texture from the bleaching, and in one treatment my hair feels super silky smooth.

Great hair treatment

It's honestly working so much better than I thought and I would honestly recommend to everyone having trouble with oily hair

Love it!

First, I'd like to say that I enjoyed the explanation on the differences between conditioners and treatments because that never really clicked for me. Also, I think it shows that Kiyoko Beauty has the best intentions for their customers by educating said customers on what may or may not work for them/what they're looking for.

I have waist-length and somewhat damaged straight hair from months of heat-styling and damaging hair styles. This treatment has definitely helped restore my hair (the only thing that would make my hair 100% healthy would be cutting it at this point). I do use it more like someone uses a traditional conditioner - everyday and only on the ponytail part of my hair - but I love it nonetheless. My hair doesn't tangle nearly as often as it did before using this product and it looks/feels a lot healthier. The scent is a bit strong when you first use it, but because it's more of a refreshing scent it doesn't trigger any allergies/reactions. The product also lasts a long time (one of my initial concerns due to the price of the product and how much conditioner I would go through). I definitely recommend giving this product a shot!

Very hydrating and smells lovely

So far using this has been a great experience -- definitely feels more luxe than my usual shampoo & conditioner. Left my hair super duper soft and my scalp feels really moisturized and cared for. Will repurchase!

Silky soft hair

This scalp treatment is excellent. Immediately when applying it, it makes my scalp feel so refreshed. The sent makes you feel like you're at a spa and after using it my hair is silky soft
