When should you use protein treatment on your natural hair ? Protein treatments should be used on natural hair when your hair shows signs of needing extra strength and repair. These signs may include: 1. Excessive breakage or shedding: If your hair is breaking easily or shedding more than usual, a protein treatment can help strengthen it and prevent further damage. 2. Dry or brittle hair: Hair that feels dry, rough, or brittle may benefit from protein to help restore its elasticity and moisture balance. 3. Lack of curl definition: If your curls or texture feel limp or lifeless, a protein treatment can help to rebuild structure and improve definition. 4. Over-processed or damaged hair: If you’ve chemically treated your hair (e.g., with relaxers, dyes, or perms), protein treatments can help repair and fortify it. However, protein treatments should not be overused, as too much protein can make the hair feel stiff, dry, and prone to breakage. Depending on your hair’s needs, using a protein treatment every 4-6 weeks is usually recommended. Always follow with a moisturizing treatment to maintain balance in your hair.
