I wonder if this product stops the dandruff hardness in the hair shedding? Also, how is the effect on keratin hair, does the keratin deteriorate?

Dandruff in our hair occurs because our scalp is very dry. Thanks to the Pumpkin Seed Oil in our shampoo, your hair is nourished, moisturized and strengthened. Keratin applied hair can also be used easily. 🙂
