We do not recommend using over the counter hair care products. Instead, you should opt for a sulfate free shampoo and conditioner that will not strip the keratin from your hair. We have several professional products that we highly recommend that will offer UV protection and added keratin to help reinforce the strength and elasticity of hair. These products are specially formulated to provide long lasting results. When you visit our Naples hair salon for your keratin treatment, one of our stylists can share specific recommendations.
