This designation is used to recognize colorists that have a greater level of competency in the industry,also in many salons they have very important jobs, they mainly have to do highlights or root touch-ups and or dying hair.
Sun protection is an important aspect of skin care. Though the sun is beneficial in order for the human body to get it's daily dose of vitamin D, if unprotected the sun can cause extreme damage to the skin, from obvious signs such as sunburn in varying degrees, early occurrences of ageing and particularly life-threatening events such as the onset of skin cancer. This is due to the skin's exposure to UVA and UVB in the sun's rays. Exposure to UVA and UVB radiation can cause patches of uneven skin tone and dry out the skin.
Beauty products are now widely available from dedicated internet-only retailers, who have more recently been joined online by established outlets, including the major department stores and traditional bricks and mortar beauty retailers.
Styling products aside from shampoo and conditioner are many and varied. Leave-in conditioner, conditioning treatments, mousse, gels, lotions, waxes, creams, clays, serums, oils, and sprays are used to change the texture or shape of the hair, or to hold it in place in a certain style. Applied properly, most styling products will not damage the hair apart from drying it out; most styling products contain alcohols, which can dissolve oils. Many hair products contain chemicals which can cause build-up, resulting in dull hair or a change in perceived texture.
