Pluck one grey hair, expect two more to grow back in its place. Pregnant women should not colour their hair. These are some of the common myths people believe in, says an expert. Medi Makeover Director & Consultant Dermatologist Suruchi Puri, has shared a list of myths attached with hair. If you pluck one grey hair, two will grow back in its place – one grey strand usually means more grey hair. This myth probably started because people plucked one grey hair, then noticed more afterwards. You can’t blame the plucking itself. Instead, it’s time to enjoy the natural colour on your head. You can’t dye your hair when you are pregnant: The main concern with dyeing your hair during pregnancy is the risk associated with inhaling ammonia. You can do some research for ammonia-free products and go for it. There are homemade solutions too. Henna has no added chemicals, and is safe to use. Using the right and luxury products will make your hair thicker: Most people think healthy looking hair is all about specific weather, costly products and styling. Your body needs a lot of energy, healthy diet, nutrients, carbohydrates and protein to grow hair. Products are required to do good cleansing and provide external moisture. Washing your hair with beer will make it softer: People believe that the malt and yeast in the beer are supposed to react well with the hair proteins, keeping it strong, shiny and bouncy. Unfortunately, the cons outweigh the pros. Alcohol dries out your hair more than the proteins repairing it. Your regular shampoo can work better and safer. Shampoo first, conditioner second: Conditioning before you shampoo your hair is great for adding nourishment to fine hair without weighing it down. Also in this reverse process, conditioner acts like a shield between your hair and shampoo and it helps so that your hair gets clean without being stripped off of all of its natural oils. Cutting your hair frequently makes it grow faster: A healthy scalp is all what you need for growing your hair well. Trimming in every eight to nine weeks can help to get rid of split ends.
