Which is the better treatment for my hair?

i just recently got the keratin hair treatment done and it was great. but instead of the blowout i got the silk. it makes your hair soft and non frizzy. my hair has usually tight frizzy curly and it was course but with the Brazilian silk my hair is soft and smooth. it is wavy but only a little bit and Ive had it for about 3 weeks. so i recommend asking your hair dresser about the Brazilian silk. good luck (:
