Keratin treatment is for damaged, rough and frizzy hair. You should always take keratin treatment for hairs.
Take biotin supplements for proper growth and good texture of hair. Get regular trimming of hair at the ends as weathering leads to dry and frizzy ends.
Avoid excessive heating procedures on hairs like straightening or dying of hair especially those that damage the hair. For now, I will suggest you do a little bit of trimming at the ends and keratin treatment will help in solving problems.
