- One way to distribute the hair’s natural oils through the hair is by brushing with a natural bristle brush. The natural bristles effectively move the oil from the scalp through to the hair’s mid-lengths and ends, nourishing these parts of the hairs. Brushing the scalp stimulates the sebaceous gland, which in term produce more sebum. When sebum and sweat combine on the scalp surface, they help to create the acid mantle, which is the skin’s own protective layer.
- Curly hair tends to dry out easily; leave-in conditioner can help. Hair that is very curly often requires careful entangling .Those with dry, curly hair should shampoo less often than those with straight hair, or consider cleaning hair with conditioner.
- Hair coloring is the process of adding pigment to or removing pigment from the hair shaft. Hair coloring processes may be referred to as dyeing or bleaching, depending on whether you are adding or removing pigment. Most permanent color changes require that the cuticle of the hair be opened so the color change can take place within the cuticle.
- Minerals in water can also affect hair.
Iron: can cause water to have a red or rusty hue. Iron leaves hair feeling dry, brittle and weighted down .It cause lack of shine and can cause dark hair to tint darker and blond hair to turn orange. Iron can inhibit the proper processing perms, colors, highlights and straightens.
