I have low porosity hair so I do have my little challenge of using the right product and right technique that works for my hair . They key in your regimen for low porosity hair is to get in and once your in, it will keep moisture longer than the others . I cannot use protein regularly , my hair will become hard because my hair is already packed with protein, so it will just be sitting on it so I try to do this only when necessary . I do my protein treatment like once or twice a year for maintenance. You can do hard protein treatment every 3 months just don't do it too frequently .
