8 reasons that lead to weak hair growth in children

    Weak hair growth in children is from the problems that mothers notice frequently, where the child's hair appears thin or does not grow at the natural speed compared to his peers. And this problem may be linked to health factors like anemia or thyroid disorders.

    Or to environmental factors like wrong habits in hair care. And understanding the reasons helps with early intervention, and preventing the problem from worsening, and ensuring healthy and thick hair growth that reflects the child's general health.

    Hair loss due to poor nutrition in children

    The first reason:

    • Protein deficiency leads to weak hair structure because it is the basic component of the hair strand.
    • Lack of intake of vitamins like Vitamin A, B, and D affects cell renewal in the scalp.
    • Deficiency of minerals like iron and zinc weakens the follicles and makes the hair susceptible to falling out.
    • The child's reliance on fast and processed food deprives the body of essential elements.
    • Drinking little water reduces hair hydration and weakens its vitality.

    Children's infection with anemia

    The second reason:

    • Anemia resulting from iron deficiency reduces the arrival of oxygen to the scalp.
    • Weak blood circulation makes the hair follicles in a state of inactivity.
    • Folic acid deficiency hinders the formation of red blood cells necessary for hair growth.
    • The feeling of continuous fatigue in the child may be a symptom accompanying hair loss.

    Hair loss as a result of genetic factors

    The third reason:

    • Genetic traits may make the hair thin or slower in growth.
    • The presence of a family history of hair problems increases the probability of their appearance in the child.
    • Heredity may determine hair density and quality since birth.

    Hormone deficiency and its effect on hair growth

    The fourth reason:

    • Hypothyroidism reduces the production of hormones regulating hair growth.
    • Imbalance in growth hormone affects the development of hair follicles.
    • Some rare cases of gland disorders may cause severe hair loss.
    • The child needs blood tests to confirm hormonal balance.

    Stress and psychological pressure in children

    The fifth reason:

    • Fear or academic anxiety may be reflected on the health of the hair.
    • Psychological traumas sometimes cause temporary hair loss.
    • Lack of sleep as a result of stress weakens the body's ability to renew cells.
    • Sensitive children may show problems in hair due to simple pressures.

    • Frequent or violent hair washing leads to its dryness and split ends.

    Children's infection with scalp infections

    The seventh reason:

    • Fungal infections like Tinea cause temporary bald patches.
    • Bacterial infections may lead to the formation of scales and pus that weaken the follicles.
    • Continuous itching leads to scratching the scalp and exacerbates the problem.
    • Lack of hygiene or sharing personal items raises the risk of infection.

    Irregular sleep in children

    The eighth reason:

    • Deep sleep helps the body produce growth hormones.
    • Lack of sleep affects the child's immunity and makes the hair weak.
    • Insomnia reduces the body's ability to renew cells naturally.
