Advanced, Keratin Bond Shampoo, Deep Repair , 20.2 fl oz (600 ml)

I have naturally black Asian hair and regularly bleach it for blonde highlights, which leaves my hair extremely damaged, dry, and broken. I’ve tried just about every product out there...from various “repair” lines to multiple Olaplex treatments, including the Hair Perfector, and nothing has truly impressed me… until now. I randomly discovered this brand through a Reddit post, and honestly, where has this been all my life?! The price, the size, the immediate results...everything about it is incredible. My hair felt so soft right after the first use. I can’t believe this isn’t getting more hype, it deserves the spotlight. The price-to-size ratio alone is mind-blowing!

It’s not the first purchase of this brand. I like the quality very much. It’s good for curly hair.

Great big size loaded with all the ingredient broken hair needs. Nice scent and practical pump that makes use rather simple.

i was going to return these tbh i got the conditioner and shampoo but tbh im glad i didnt have to because these are actually so good like it genuinely does repair my hair which is so insane because olaplex couldnt even do anything for me. i had pretty bad chemical breakage but since using these products i can see how it genuinely bonds my split ends together and makes them more resilient so i can retain length while im growing my hair back out, and it's affordable too so that's great

my experience with this shampoo and it's conditioner is the best i ever had so far. I have wavy freezy hair, and these products are the best shampoo and conditioner for my freezy hairs so far.

I really like this product but it needs to be wait to see the result need to be patient

Bought it for my mon with weary and processed hair. Her feedback is quite positive she says her hair is much smoother now. Recommended

One of the best iHerb products, and I love it very much. waw

I’ve been using this Keratin Shampoo for a while now, and I’m really impressed with the results. The texture is smooth and easy to apply, and it creates a nice, gentle lather without feeling heavy. After washing, my hair feels soft, silky, and much easier to manage. I’ve noticed that it helps reduce frizz and gives my hair a natural shine. It also makes my hair feel stronger and healthier, which is exactly what I was looking for in a keratin-based product. The scent is pleasant and refreshing, not too strong, and it lasts throughout the day. Overall, this shampoo is a great choice for anyone who wants smoother, shinier, and more nourished hair. I would definitely recommend it!

The Shampoo is just ok. I think I need something more for dry hair. It does smell good. My husband can use it.
