If your hair has lost almost all elasticity and/or looks and feels "spongy" or "mushy," this treatment could help. You must follow all directions carefully and follow the treatment up with an intensely moisturizing conditioner for the best results.
After a protein and moisture dose, assess your hair. Its condition may be significantly improved or not much at all. If you don't see much of an improvement, do not reapply a strong protein treatment. Your hair still needs protein, but not in such an intense application. Instead, products containing protein can be applied on a weekly or biweekly basis to keep your hair strong. Too much protein will dry your tresses out and lead to breakage, so please don't overdo it, no matter what condition your hair is in.
