Hair is the crowning glory of one’s appearance, and the scalp determines its quality. Are you experiencing any issues with your hair? Excessive sebum production, dandruff, itching, red bumps, or hair loss? Every morning or after showering, when you see the hair all over the bed and floor, and notice the receding hairline, do you worry about going bald at a young age? Will cutting your hair shorter help reduce hair loss? Why does using a new anti-dandruff shampoo sometimes make the problem worse? As the saying goes, “Without skin, hair has no place to grow.” Hair has its own growth cycle, which generally consists of three phases: anagen (growth), catagen (regression), and telogen (rest). In healthy adults, most hair is in the anagen phase, with a total of about 100,000 hairs. Under normal circumstances, a healthy adult loses 50-100 hairs per day, which is considered normal hair loss. However, if you lose more than 100 hairs daily, the balance of hair growth is disrupted, leading to thinning or even localized baldness. This not only affects your appearance but also causes psychological stress and mental strain. This type of excessive hair loss is known as “pathological hair loss” and requires attention and treatment. The scalp, being part of the skin, has its own protective barriers: the stratum corneum and the oil secreted by the sebaceous glands, which together form a barrier that protects against external stimuli and retains moisture. When this barrier is damaged, issues such as itching, redness, and excessive oil production can occur. Dandruff is often related to a weakened scalp barrier. Studies have shown that dandruff sufferers have lower lipid levels between the cells of the stratum corneum. Therefore, increased sebum production, an imbalance in the scalp microbiota, and a damaged scalp barrier all contribute to dandruff and an unhealthy scalp condition. How to improve your hair health: 1. **Proper hair care:** Choose the right shampoo for your scalp type and wash your hair regularly. You can gently massage your scalp with your fingertips or a comb while washing. 2. **Keep your scalp fresh:** Blow your hair dry properly, wear hats less, use fewer styling products, and get more sun exposure. 3. **Dietary adjustments:** Maintain a balanced diet, drink enough water, and consume moderate amounts of fats to keep the scalp’s moisture balance. 4. **Lifestyle habits:** Get enough sleep, reduce stress, and exercise regularly. 5. **Regular maintenance:** Use anti-dandruff and exfoliating products for your scalp. 6. **Medical interventions:** Topical medications like minoxidil can promote hair growth; oral medications like spironolactone (for some women with androgenetic alopecia) and finasteride (for men) can reduce hair loss. Autologous platelet-rich plasma and low-energy laser therapy can also be effective. 7. **Nutritional supplements:** Omega-3 fatty acids nourish hair and prevent dryness and loss; vitamins and minerals support hair growth; foods rich in iron, such as red dates, can improve blood circulation and prevent hair loss; AKG can nourish the scalp and improve hair health, even turning gray hair black. AKG helps you with your hair health in the following ways: 1. **Protect against free radical damage:** The scalp is exposed to environmental factors like UV radiation and air pollution, which generate free radicals that can damage scalp cells, leading to aging and hair problems. As an exogenous antioxidant, AKG can break down the structure of H₂O₂, reducing its oxidizing toxicity and preventing damage to scalp cells. 2. **Enhance the body’s antioxidant defense system:** AKG strengthens the scalp’s natural antioxidant defenses, helping it better resist oxidative stress and maintain healthy cell function. 3. **Support stem cell function:** Healthy hair follicle stem cells are essential for hair growth. AKG supports their activity, providing a good foundation for hair growth. 4. **Promote cellular energy metabolism:** AKG provides energy to scalp cells, promoting their metabolism and self-repair, which helps maintain scalp health and reduces hair loss. 5. **Accelerate wound healing:** AKG promotes wound healing in damaged scalps, reducing scarring and restoring the scalp to its normal state. 6. **Maintain scalp pH balance:** The scalp’s pH level is important for its health. AKG helps maintain a slightly acidic environment, which inhibits harmful bacteria and promotes the growth of beneficial bacteria, reducing dandruff and itching. 7. **Regulate sebum production:** AKG regulates sebum secretion, keeping it in a balanced state. This helps to moisturize the scalp and prevents pore blockage and folliculitis. 8. **Repair damaged scalp tissue:** AKG reduces inflammation and promotes the repair of damaged scalp tissue, lowering the risk of hair loss. 9. **Improve blood circulation:** AKG increases glutathione levels in red blood cells, improving blood circulation to the scalp. Better blood circulation provides nutrients and oxygen to the follicles, promoting healthy hair growth. 10. **Clinical research:** Studies have shown that long-term AKG supplementation improved the hair color and quality in middle-aged female mice, with some even experiencing hair turning black, and reduced hair loss.
