How many hairs does a person really have in their lifetime? According to scientific estimates, an adult has approximately 90,000-150,000 hairs, and they are replaced every 2-6 years, with each hair having a lifespan of about 3 years. When hair enters its final life cycle, it naturally falls out. Hair shedding is a normal physiological phenomenon, but if the amount of hair loss increases or your hair becomes increasingly dry, you should pay attention, as this could be a precursor to thinning hair or baldness.
How much hair is it normal to lose daily?
A normal person loses about 50-100 hairs daily. If you don't exceed this amount each day, it won't lead to thinning hair or the risk of hair loss. Losing 100 hairs might sound like a lot, but because normal hair is quickly replaced by a similar number of new hairs after shedding, there's no need to worry. Additionally, the simplest test method is to gently pull a small strand of hair with your hand. If more than 5 hairs come out, and this situation persists for more than 3 months, there might be a risk of hair loss, and you should pay attention!
Causes of Hair Loss
Genetics: Family history factors, more common in men, androgen-dependent inheritance.
Stress: High life stress and emotional instability can lead to endocrine disorders causing hair loss.
Malnutrition: Anorexia, bulimia, or eating disorders can lead to insufficient protein/iron, affecting hair growth.
Hormonal Secretion: During pregnancy, childbirth, or menopause, changes in the body's endocrine system can affect hair growth.
Medications: Blood pressure medications, birth control pills, steroids, anti-thyroid drugs, etc., can have hair loss as a side effect.
Tight Hairstyles: Consistently pulling hair tightly can lead to gradual hair loss.
Scalp Health: Excessive oil on the scalp can block pores and affect hair growth.
Hair Loss Can Be Prevented! 5 Hair Care Secrets
1. Scalp Massage
To have healthy hair, you can start with scalp care, and massage is one effective method, though it requires persistence. First, place your fingertips on your head and slowly press backward from your forehead. Don't apply too much force. Massage to the top of your head and the back of your skull to stimulate the scalp and promote blood circulation.
Additionally, there are many massage wooden combs on the market; choose those with air cushions and thicker bristles. Regular combing not only prevents hair from tangling but also stimulates acupoints on the head to massage the scalp.
2. Relax Your Mind and Body
City dwellers face a lot of stress in work and life every day. Stress causes the body to secrete more male hormones to help us have enough energy to complete our work. However, an increase in male hormones also increases sebum secretion, including on the scalp and various parts of the body, which can accelerate hair loss.
Therefore, you should try to relax your mind and body after work or on holidays, ensure you get enough rest, and doing more aerobic exercise can also help reduce stress.
3. Dry Hair Before Bed
Taking a hot shower before bed can help with sleep and feel more comfortable, but going to bed immediately with wet hair can not only easily cause headaches but also lead to hair loss and dandruff. Therefore, it's important to dry your hair before bed.
4. Avoid Tight Hairstyles
Frequent or tight hairstyles can damage hair roots. You should often allow your scalp and hair roots to relax, especially not tying your hair tightly when sleeping, and avoid excessive pulling of hair.
5. Balanced Diet
As the saying goes, "What you eat, what you are!" You should maintain a balanced diet, consume various nutrients, and avoid excessive dieting for weight loss. Reduce intake of greasy, high-sugar foods. Eating more fruits, boiled eggs, natto, salmon, shellfish, almond paste, etc., can effectively prevent hair loss.
5. Choose the Right Shampoo
To prevent hair loss, you must first maintain scalp health. First, choose a mild and natural shampoo to reduce chemical irritation to the scalp. If you have an oily scalp, choose a shampoo for deep cleansing and oil control to prevent oil from blocking hair follicles and affecting hair growth.
Although shampoo does not have hair growth efficacy, choosing a shampoo suitable for your scalp and with natural ingredients can help prevent hair loss and maintain strong hair strands.
