Soft rebonding

 Soft rebonding, on the other hand, uses low temperatures to reduce thermal damage. The harsh chemicals used in the original rebonding also damage the lock, making thehair weaker and more fragile.

Brazilianstraightening treatments are designed to remove most or part of the curly hair and smooth out curls and waves. Theycan be performed on all hair types, whether naturally or chemically treated (bleached,highlighted, colored, permed, relaxed, or previouslystraightened). The effect usually lasts about three months. Treatment must be repeated every few months to straighten the new hair growth.
