People care for themselves from head to toe, making hair care particularly important. The bare minimum is maintaining clean hair. However, excessive washing can cause bodily issues, and improper hair care can also harm your health.
Avoid Washing Hair in the Morning During Fall and Winter
Due to busy daytime schedules, many prefer washing hair at night or before morning commutes. Yet sleeping with wet hair or exposing it to cold winds poses significant health risks.
After a full day's work, fatigue greatly reduces the body's ability to resist illness. Washing hair at night without thoroughly drying it allows moisture to linger on the scalp. Over time, this can lead to stagnant qi and blood stasis, blocking the meridians.
In winter, when cold and dampness combine, this becomes an even greater health hazard. Some who habitually sleep with wet hair may eventually experience localized scalp numbness accompanied by vague headaches. Others may wake the next morning with headaches and tingling, becoming prone to colds. Over time, persistent exposure can lead to noticeable numbness on the crown, along with dizziness and headaches.
Washing hair before leaving home in the morning is also inadvisable, especially during cold winters. With hair left damp and pores open, the head becomes vulnerable to wind and cold. Even mild exposure can lead to colds and headaches. Repeated instances may cause joint pain or even muscle paralysis.
If you habitually wash hair at night or in the morning, ensure it is thoroughly dried before sleeping or going out.Women should thoroughly dry their bodies and hair after bathing to prevent cold pathogens and dampness from invading, which can cause headaches, neck/back/waist pain, or even gynecological issues. "Regardless of when you wash your hair, avoid sleeping or going out in cold winds before it's dry. This prevents stagnation of qi and blood in the head, which can block meridians and lead to dizziness, headaches, and other ailments,"" said Wei Liang, Associate Chief Physician and cardiovascular disease specialist at Huizhou Union Hospital of Southern Medical University.
Bring Your Own Shampoo to the Salon
Regular salon-goers should bring their own high-quality shampoo to prevent inferior products from lingering on the scalp, which can cause hair loss and breakage.During the wash, request that the stylist wear disposable gloves when massaging your scalp. Avoid excessive scrubbing, which can damage hair follicles and lead to cross-contamination of bacteria, causing scalp inflammation. Individuals with cervical spondylosis should avoid lying flat on their backs for extended periods during washing to prevent carotid artery compression and insufficient blood supply to the head.
Frequent Hair Washing Is Not Recommended
Have you ever felt like you just can't stop washing your hair? If you skip a day or two, you might experience scalp itchiness, increased dandruff, and sometimes even hair loss.
Dermatologists suggest these symptoms may stem from frequent shampooing habits, medically termed "shampooing syndrome." Most commercial shampoos contain strong alkaline cleansing agents. While generally harmless during brief contact, prolonged exposure in salon settings can irritate skin.Compounded by the prolonged massaging and scrubbing by salon staff, these alkaline agents can penetrate hair roots and follicles, damaging hair and irritating the scalp. This leads to itching and increased dandruff, with severe cases resulting in hair loss. Regular salon-goers should adjust their habits to avoid these symptoms and achieve the intended relaxation of a shampoo session.
Common Hair Washing Misconceptions: Are You Aware?
Misconception 1: Daily shampooing damages the scalp and dries out hair because hair care products contain excessive chemicals.
Wrong!With advancing technology, high-quality hair care products now feature chemically balanced formulas with appropriate pH levels. Extensive clinical studies confirm daily use causes no irritation or harm to the scalp. Conversely, quality products form a protective barrier on the scalp that outperforms natural sebum.
Myth 2: Daily washing causes hair loss.
Wrong! Hair roots are embedded deep within the scalp, largely unaffected by external factors applied to the hair shaft. High-quality shampoos and conditioners do not cause hair loss or disrupt the hair growth cycle. Only harsh washing techniques can lead to hair loss.
Misconception 3: Freshly washed hair lacks volume, but looks better after a couple days when it gets oily.
Wrong! Freshly washed hair appears frizzy and unmanageable because natural oils haven't yet distributed from the roots to the shafts. By the time oils reach the ends, they've likely absorbed dirt and grime, posing risks to both health and appearance. To combat frizz, use a separate conditioner or leave-in conditioner.
Misconception 4: Sleeping with wet hair causes headaches, while blow-drying damages hair.
Wrong! There is no scientific evidence that sleeping with wet hair causes headaches or colds. If you prefer dry hair before bed, first blot excess water with a towel, then use a hairdryer on low heat to finish drying. As long as you keep the dryer moving and maintain a distance of at least 10 centimeters from your hair, it won't cause damage.
