My hair is really frizzy in nature and when i have bad hair days it is the worse. Using a ironing hair straightener does not help much, as after some time my hair comes to its previous nature . And then when this happens my hair is dificult to control and make peace with. My beautician then suggested me that why dont i try a keratin treatning.Since i have never used keratin complex, i want to know how does keratin help the hair? Will it make my hair straight and even smooth? Will Keratin treatment have any side effects? If there are ,please tell me so that i have a well rounded knowledge about the keratin treatment before i go for Keratin Treatment.
