What Is Keratin For Your Hair? Keratin is a natural type of protein in your skin, hair, and nails. A keratin treatment adds additional keratin to your hair, which can help to reduce frizz, increase shine, and strengthen hair. If you have curly or wavy hair, keratin treatments can also make your hair straighter.
Does keratin cause hair loss? It is a well-known fact that Keratin treatment may result in breakage of hair. This is due to the fact that the treatment uses high heat that may make hair strands appear beautiful, but will ultimately result in hair damage and breakage.
How long do keratin treatments last? Long-lasting results As long as you care for a keratin treatment by not washing your hair too frequently (2 to 3 times a week is enough), then your keratin treatment can last up to 6 months.
