Do you worry about the hair falling out of the comb after brushing your hair every day? In fact, it's perfectly normal to lose an average of 50 to 100 hairs a day, according to the American Academy of Dermatology. The amount of hair you have is determined by your genetic makeup. Basically everyone loses hair as they age because hair growth slows down with age. However, if you lose more than a certain amount of hair per day, then you should be concerned. First of all you should know what causes hair loss.

People experience different types of hair loss, including:

Hormonal changes: the most common culprit in women. This usually happens when you start oral contraceptives, after giving birth (about four months postpartum) and during menopause. Conditions that are affected by hormones such as polycystic ovary syndrome, thyroid problems, and even stress can also cause hair loss.

Inflammatory hair loss: Another very common cause of thinning hair is an inflamed scalp. "It's common in dandruff, where patients experience itchy, flaking, and irritated scalps," explains Dr. Fusco, adding that conditions such as psoriasis and even fungal infections can lead to thinning hair if symptoms are not treated.

Telogenital Alopecia: This is the second most common cause of hair loss. Telogen effluvium occurs when a person has a reduced number of hair follicles, causing their hair to fall out. Occasionally, a triggering event (such as a serious illness) occurs. Using mild shampoos and oils along with specific nutritional supplements may help relieve this condition.

Chemical-induced hair loss: High-frequency treatment of hair with strong chemicals and dyes can cause hair loss. Changing these practices may help prevent further damage.

Nutrient deficiencies: For healthy hair, the key nutrients are healthy levels of iron, zinc, ferritin, folic acid, and vitamin D3, which one can obtain by following a healthy diet and taking related supplements. Nutritional hair loss is the most prominent form of hair loss worldwide and the easiest to correct. Nutritional hair loss causes generalized thinning of the entire scalp and may exacerbate other types of hair loss.

According to dermatologists, the following shampoos, oils, and supplements are the best products for thinning hair.
