Necessary items: a comb, a mirror, a lamp (pay attention to let the light shine from the top of your head, and the sun can also do it)
Operation method: Clean hair with mild shampoo, and use hair moistening products at the same time, but be careful not to use styling products that increase the burden on hair. Separate the washed hair and comb it flat and smooth. Put a mirror directly opposite, so that you can see your head clearly from the inside. Make the light shoot down from the top of the head, forming a crown-shaped halo.
Inference: The brighter the halo, the better the luster of the hair. Because carefully cared hair is often smooth, with a smooth surface, which can reflect the light shining on it well and give off luster. When the hair is curly and dull, the light is scattered, so it looks dull. Comb your hair from side to side. If the gloss of the hair is really good, as the hair slides, you will see the halo on the top of your head sliding. If you have curly hair, the light will reflect the light at the top of the curly hair. If there is no halo, you should implement the following scheme to polish your hair.
Polishing prescription: Use some care products containing silicone or dexpanthenol (or both) to make your hair brighter. In addition, the proper use of styling products with shine effect will also add points to the luster of hair.
