Not the best
Very mid product. I prefer the k18 peptide shampoo by a long shot. Seems like they changed the formula for damage shield. Side note: it does contain sodium chloride so don’t use on a keratin!

Smoother and shinier hair
I have dry fuzzy hair. After using this for some time my hair is smoother and shinier. I use the shampoo and conditioner. I’m really impressed. It gradually improves over time as tge scalp gets more healthy so don’t expect it immediately.
