DR.RASHEL Keratin Shampoo is likely a hair care product formulated with keratin as a key ingredient. Keratin is a protein that naturally occurs in hair and helps strengthen and protect it. Keratin shampoos are designed to nourish and repair damaged hair, reduce frizz, and promote smoothness and shine.

This shampoo may be particularly beneficial for those with chemically treated or heat-damaged hair, as keratin can help restore the hair's strength and elasticity. Additionally, keratin shampoos often contain other conditioning agents and vitamins to further enhance hair health.

As with any hair care product, it's essential to read the instructions and ingredients carefully to ensure it meets your specific hair care needs and to avoid any potential allergic reactions.
