Hair health care guide pdf

90% of daily hair problems (excessive oil production, dandruff, mild hair loss, frizzy split ends) can be solved by "cleaning and adapting to the condition of the scalp + protecting the scalp hair barrier + regular work and rest". The remaining 10% of pathological hair loss, alopecia areata, repeated large-area dandruff and other problems should be consulted by a dermatologist as soon as possible. Don't spend money on folk remedies.

I have been doing offline scalp care for 3 years, and I have seen too many people take detours in hair care: some people change three kinds of Internet celebrity shampoos a week to prevent hair loss, some people rub ginger on their scalp every day until it becomes red and ulcerated, and some people still stock up on hundreds of dollars a bottle of "hair growth essence" even though they have male hair loss. They have spent thousands of dollars, and their hair should fall out or fall out.

To be honest, the most controversial issue I have ever seen is "Can I wash my hair every day?" The related issue has received nearly 10 million views on the platform, and the two sides are quarreling. The mainstream view of dermatology is that it is best to wash your oily scalp every day to avoid accumulation of oil and clogging the hair follicles, aggravating oil production and even causing folliculitis. ； The traditional care school believes that frequent hair washing will destroy the sebum film of the scalp, making it oilier the more you wash your hair. In fact, is there any standard answer? After a day of running outdoors in the summer, your head is sweaty. Even if you have dry skin, you still need to wash it. Otherwise, the residual sweat and dust will become stuffy on your scalp and cause problems. ； After spending a day in a climate-controlled air-conditioned room in winter, my scalp didn’t feel oily at all, and it was perfectly fine to wash it every other day. There’s really no need to stick to the “must wash it every other day” rule.

Oh, by the way, many people suffer from dandruff and oiliness. It’s not the shampoo that’s the problem at all, it’s the wrong way of washing. Last time, a young girl born in 2000 came to me and said that she had so much dandruff that "it started to snow" when she shook her head. I peeled off her hair and saw that the hairline was full of residual shampoo clumps. When I asked, I found out that every time she washed her hair, she poured the shampoo directly into the top of her head, rubbed it twice and then rinsed it off. She didn't even touch the back of her ears or the back of her head. I asked her to go back and soak the shampoo in her palms before applying it to her scalp. She washed it for 3 minutes each time and rubbed all the dead spots. After only 10 days, she sent a message saying that the dandruff was basically gone. Some people are used to picking their scalp with their fingernails, thinking that they can wash it clean this way. In fact, the bacteria in the nail gaps can easily scratch the scalp and cause infection. The correct way is to use your fingertips to press in circles, and the intensity is about as strong as you usually rub your face.

There is another topic that has been debated for many years: Is silicone oil an IQ tax? In the past few years, the entire Internet criticized silicone oil for blocking hair follicles and causing hair loss. In the past two years, silicone oil has been used to nourish hair. There are a lot of arguments on both sides. Objectively speaking, silicone-free shampoo is more suitable for people with oily scalp and scalp acne-prone people, and the refreshing feeling will last longer after washing. ； Cleansing and care products containing silicone oil are more suitable for dry and frizzy hair that has been damaged after perm and dyeing. Silicone oil will fill the gaps in the hair cuticles, making it smoother to the touch. I have medium-to-dry hair. After I had my hair permed last year, I have been using silicone-containing conditioner. My hair has never split ends. I followed the trend and switched to silicone-free hair care for half a month. My hair was as dry as hay, so I quickly changed it back. There is really no need to listen to marketing nonsense. The best one suits you. Oh, and by the way, unless you are a super oilfield, don’t touch those Internet-famous shampoo soaps and strong soap-based shampoos. Long-term use will destroy the weak acid environment of the scalp, making it dryer with more washing. I have seen several customers with dry skin use the shampoo for half a month, and they have so much dandruff that they want to wear a hat every day.

The care after washing is actually not that particular. Many people ask whether conditioner can touch the scalp. This does not need to be absolute: if you have dry skin and use a refreshing conditioner, it doesn’t matter if it touches the scalp a little. Just rinse it off. If you have oily skin, which is prone to clogging hair follicles, try to only apply it to the ends of your hair to avoid getting oily and frizzy half a day after washing. When blow-drying your hair, don't turn on the hottest setting and blast it toward your scalp. The hair scales are like the scales on a fish. They are slippery when you touch them. If you touch them against the opposite direction, you'll shave your hands. Blow-drying your hair at temperatures above 100 degrees is equivalent to prying up these scales piece by piece. When scales fall off over time, your hair will become frizzy and split, and it won't be repaired no matter how you repair it. It's enough to blow on the warm wind setting until it's 80% dry, and let the rest dry naturally, which saves time and won't damage your hair.

Oh yes, there is another point that everyone easily overlooks: scalp sun protection. Many people apply sunscreen on their face, arms, and legs in summer, but forget about their scalp. You must know that the thickness of the scalp is thinner than the skin on the face. Direct ultraviolet rays will not only cause redness and peeling, but also destroy the activity of hair follicles. I had a client who went to Sanya for 3 days last summer. He found it troublesome to wear a hat and did not use sunscreen on his scalp. After returning, he suffered from dandruff and tripled his hair loss. It took him almost 3 months to recover. Wearing a hat or an umbrella when going out in summer is more effective than any amount of anti-hair loss serum you use.

Another controversial point is whether or not you should comb your hair every day. The school of traditional Chinese medicine believes that combing your hair can stimulate the scalp acupuncture points and promote circulation. It is recommended to comb your hair dozens of times a day.； However, the view of modern dermatology is that over-combing your hair will pull out healthy hair, especially if you have a risk of traction alopecia (such as wearing a high ponytail all year round). If you comb your hair too much, you will lose more hair. My own experience is that if your hair is not tangled, just comb it for 10 strokes to smooth it out. There is no need to impose a KPI of 100 strokes. If your hair is easy to tangle, use a wide-tooth comb to slowly comb it out and don't pull it hard. The hair that is pulled out will not grow back.

Many people say that staying up late will cause hair loss, and there is indeed a basis for this: staying up late will cause androgen secretion to fluctuate. People with androgenic genes will lose hair three times faster than ordinary people. But don’t be overly anxious. If you are a natural night owl and go to bed at 2 a.m. and start at 10 a.m. every day, and have a regular schedule, the impact on your hair is actually much smaller than that of someone who lies in bed from 11 a.m. to 3 a.m. and is still awake. The key is the regular schedule, not the standard of “going to bed before 11 a.m.”

Finally, let’s talk about the 10% of pathological problems at the beginning: If you lose more than 100 hairs every day for 3 consecutive months, have obvious receding M-angle, have patches of hair loss on your scalp, and have dandruff repeatedly, no matter what shampoo you use, don’t believe in the myths about ginger hair rubs, anti-hair loss shampoos, and hair growth essences. Go directly to the hospital for dermatology and spend tens of dollars to do a hair follicle test. Minoxidil and finasteride are effective ingredients certified by the FDA. If you have any problems, just follow the doctor’s advice. I once had a 28-year-old male client who had his M-horns moved back for almost two years. After applying ginger for half a year, his hair follicles shrank. Later, he went to the hospital for a hair transplant to save his hair, which cost him tens of thousands of dollars.

In fact, hair care is really not that complicated. Don’t be led away by the anxiety created by marketing. Pay more attention to the condition of your scalp. It is much more useful than following the trend and buying 10 bottles of Internet celebrity products. If you are really worried about hair loss, go to the hospital for a test first, it is much more reliable than just guessing.
