Wash Hair with Shampoo Only Once “The first thing I would never do is wash my hair with shampoo only once — always twice, and sometimes even three times,” says the hairdresser. According to her, this is very important because the “first shampoo” only removes external dirt, while the second and third cleanse the scalp. Use Shampoos with Silicone “I know that not everyone can afford professional shampoos and conditioners. But if you use something without silicone, at least you are taking a step in the right direction,” the specialist believes. Silicone is a substance that coats each hair with a thin film, smoothing the keratin scales and filling in gaps, which makes the strands smooth and shiny. However, according to the hairdresser, this advantage is also a disadvantage: silicone clogs the pores of the skin, which can slow down hair growth and prevents nourishing components from penetrating deep into the hair structure. Go to Bed with Wet Hair This should not be done because wet hair is most vulnerable, and friction against the pillow can seriously damage it. But that’s not all: due to excessive cooling at night, hair follicles can become inflamed, leading to hair loss, redness, itching, and even pustules. Additionally, the scalp can harbor the Malassezia Furfur fungus, which thrives in humid conditions and causes dandruff and skin flaking. Style Wet Hair “Never, hear me, never straighten or style wet hair — this is very important! If you hear sizzling, it means you just got a burn, and unfortunately, the hair does not heal. You will either have to cut it, or it will remain dead and lifeless forever,” explains the hairdresser. This is indeed the case: curling irons and straighteners heat up to a hundred degrees or more. By using them, you literally boil the water trapped inside the hair strands, and such a procedure can easily damage the locks.
