WHAT’S IN IT
Can overuse of Keratin can make hair brittle?
False. Keratin amino acids are the primary building blocks of human hair and help maintain hair’s core strength, moisture balance and elasticity, all vital to protecting hair against damage and breakage. Keratin Repair has an abundant amount of keratin amino acids that make your hair visibly stronger, shinier and healthier with each use. It is not possible to make hair brittle with, or to overuse, keratin amino acids.
