I can only imagine that your hair is chemically over processed or that it is seldom trimmed to have such brittle tips. Perhaps even ironing it without a thermal protector. I recommend a trim to get the brittle ends off as they "creep" up the hairshaft causing severe splitting. In addittion, I would recommend the use of a thermal protection product with humidity resistance which holds the style for longer, like Redken IRON SILK 08. Ensure that your hair is properly dry before ironing. Damp hair frizzes in minutes! Your hair fall is a completely different issue and I would like more info… your age, diet, chemical services you have had the past year?
