Lack of sleep can cause telogen effluvium, a condition that results in excessive hair shedding. The body's stress response can push hair follicles into a resting phase, causing them to shed prematurely. Sleep deprivation can disrupt the body's natural hair growth cycle and reduce the production of growth hormones. Studies show that people who sleep less than six hours per night experience higher levels of hair shedding. Poor sleep quality can cause hair loss and dryness, making hair prone to breakage. Practicing good sleep hygiene is crucial to maintain healthy hair growth.

Stress-induced hair loss occurs due to disturbances in the natural hair growth cycle. Hormones like cortisol, adrenaline, and norepinephrine released in response to stress can affect hair follicle growth by causing them to enter the resting phase or telogen phase, leading to hair fall. Inflammation triggered by stress can damage hair follicles and impair growth, while the reduced blood flow to the scalp can starve hair follicles of essential nutrients, causing hair thinning. Chronic stress can also result in alopecia areata, an autoimmune disorder that causes hair loss. A balanced diet and relaxation techniques can mitigate the negative effects of stress on hair health.

Healthy hair growth and preventing hair loss depend on adequate nutrition. Hair is primarily made up of the protein keratin, which requires several nutrients for growth. Protein-rich foods, such as eggs, fish, and legumes, provide the building blocks for keratin production. Vitamins, including biotin, vitamin D, and vitamin E, promote healthy hair growth, while minerals like iron, zinc, and selenium are crucial for oxygen transport, repairing damaged hair follicles, and protecting hair follicles from damage. A balanced diet rich in these essential nutrients and a healthy lifestyle can help prevent hair loss and promote healthy hair growth.

Healthy lifestyle and habits are crucial for preventing hair loss and promoting healthy hair growth. Stress, diet, physical activity, sleep, and hair care practices can all affect hair health. Chronic stress can lead to hormonal changes that disrupt the hair growth cycle and cause hair fall. A diet rich in protein, vitamins, and minerals, including biotin, vitamin D, vitamin E, zinc, iron, and selenium, is essential for healthy hair growth. Regular exercise promotes blood flow to the scalp, while adequate sleep is crucial for overall hair health.

Male pattern baldness, or androgenetic alopecia (AGA), is the most common type of hair loss in men and is heavily influenced by genetics. The androgen receptor (AR) gene determines hair follicle sensitivity to dihydrotestosterone (DHT), a hormone that contributes to hair loss. Genetic variations in hair follicle development, inflammation, and wound healing can also impact hair growth. Environmental factors, such as stress and diet, can also affect the severity of AGA. Treatments such as minoxidil and DHT blocking serum can help slow its progression.
