Why Hair Falls Out: Causes in Men and Women

How much hair loss per day is normal?

Losing between 50 and 100 hairs per day is part of the natural hair renewal cycle. The problem begins when this loss accelerates, more hair is noticed on the pillow, brush or shower drain, or when areas of lower density appear. Identifying this difference is the first step to acting in time, before hair loss becomes more difficult to reverse.

Most common causes in men

In men, the most frequent cause is androgenetic alopecia, linked to the sensitivity of follicles to dihydrotestosterone (DHT). This causes progressive thinning, usually at the temples and crown. Added to this are factors such as stress, a diet poor in micronutrients, and deficiencies of zinc, iron or biotin, which weaken the hair fiber even before genetics manifest strongly.

Most common causes in women

In women, hair loss is usually more diffuse than localized, and is highly influenced by hormonal changes: postpartum, menopause, thyroid alterations or contraceptives. Chronic stress and restrictive diets are also common triggers. Unlike men, it rarely leads to total baldness, but it does lead to a loss of density and thickness that visibly affects hair volume.

The role of nutrition

In both men and women, hair is one of the first indicators of nutritional deficiencies, because the body prioritizes other vital functions before hair growth. Biotin promotes keratinization, zinc and selenium participate in follicular cell repair, and plant extracts such as saw palmetto help moderate the effect of DHT naturally. That is why food supplements specifically formulated for each sex—such as Xpecia Men and Xpecia Women—have become a common support within hair care routines, complementing (not replacing) a balanced diet.

When to consult a specialist?

If hair loss is sudden, in clumps, or is accompanied by itching, scaling or pain in the scalp, it is advisable to consult a dermatologist before starting any treatment on your own. For progressive and hereditary pattern hair loss, however, acting early with a consistent routine—adequate cleansing, nutritional supplements and, if necessary, topical treatments—usually gives better results than waiting for the problem to advance.

How to build a hair care routine

A basic and sustainable routine combines three elements: a gentle shampoo that does not harm the scalp, a nutritional supplement adapted to your sex and needs, and, if hair loss is already visible, a lotion or spray with specific active ingredients. Consistency is more important than intensity: results in hair density and strength usually begin to be noticed after the eighth or twelfth week of continuous use.

Conclusion

Hair loss rarely has a single cause, and understanding whether the origin is hormonal, nutritional or genetic helps to choose the correct treatment. While a dermatologist is the best option for warning signs, in cases of progressive hair loss linked to age or nutritional deficiencies, a specific food supplement for men or women, along with a good care routine, is a first step supported by available evidence.
