Prolonged use of keratin treatments can cause allergies, irritation, or flaking of the scalp.
• It can only be used on thick, coarse hair, since the straightening treatment is aggressive and can break it or cause split ends.
• The treatment is expensive, and if you get it done at a beauty salon, it's even more expensive. Additionally, depending on the type of keratin treatment you choose, the cost may vary.
