Q. Non-silicone products are getting attention. Is silicone really bad for hair?
Silicone in shampoo coats the surface of the hair, just like manicure does to nails, so it makes the hair look shiny temporarily. Most cosmetic products, not just shampoo and conditioner, contain silicone. Most products go through clinical demonstration, so it is not a problem. Many consider among silicone, dimethicone or methicone are harmful, but the evidence is hard to find. Dimethicone is in charge of moisturization in shampoo or other cosmetic goods. FDA classifies it Class 1 (safe and effective), and as long as it is within 0-30%, it is safe to use from babies to adults. According to the report on dimethicone on International journal of toxicology, it is safe to use. There are findings that it can be harmful when consumed, but the opinions differ on this matter.
Q Will functional shampoo alone provide ample nutrition to scalp and hair?
Functional shampoos, such as oriental medical shampoo, can help scalp and hair, but shampoos are shampoos, not treatment. In order for functional shampoos to have effect, the ingredients must penetrate into hair follicles, but they are deeper than expected and harder to reach. Especially for effects of hair growth, it is advised to get medical help. If you wish to actively take care of the health of scalp and hair, check the condition with a professional dermatologist and receive scalp care.
Q Is it a good idea to wash hair in the evening?
Many wash their hair in the morning to easily style their hair, but if you are considering the health of scalp, it is advised to wash hair in the evening. The dirt and sebum, styling products can block pores and cause troubles. They can be the cause of dandruff and HAIR LOSS, so to finish a day with a clean hair is good for scalp health.
Q Is dyeing a hair the cause of HAIR LOSS?
Generally hair loss has no relation to hair dyeing. When one dyes a hair, the color changes from the scalp to within 1mm, but even so, this does not cause hair loss. However, if the scalp is sensitive or if one changes hair styling too often by dyeing or getting a permanent, the scalp can be irritated. If irritation is repeated, hair loss can be expedited, so extra care is needed.
Q Is it true that picking a prematurely gray hair will cause the hair to never grow?
The most common saying about prematurely gray hair is that picking it out will cause the hair to never grow. It is reasonable in the long term. The hair that comes out of one pore of the scalp is around 25~35 for the whole life. Each hair lives for about 2~3 years. If you pick out a prematurely gray hair, the life cycle of hair becomes distracted, and can cause hair loss. It is wiser to cut a prematurely gray hair, than to pick it out.
Scalp and hair are the areas that need daily care, just like facial skin, but are easy to overlook. Choose scalp, hair products according to one’s own scalp and hair type. Choose a shampoo that can recover the scalp’s metabolism on its own, rather than the one with strong sterilization.
If the hair is damaged due to frequent dyeing, it is advised to use acid shampoo. Slightly acid shampoos (Ph5~6) will suppress hair’s swelling and slow down penetration to the skin, and thus making the hair shiny. If you have a lot of dandruff, use dandruff shampoos that contain 2~3% zinc pyrithione in order to suppress pityroporum ovale. These dandruff shampoos controls itchiness and dandruff. If you are worried about hair loss, choose a shampoo that FDA has approved, and it will help with hair loss.
