The more pregnant you are, the more likely you are to experience hair loss?

“I lost my hair with my first baby, but it all recovered, but after my second baby, it hasn’t recovered.”

“It seems like the more you have children, the thinner your hair becomes.”

This is a story I often hear from mothers with multiple children in the clinic. Postpartum hair loss from a single birth is a huge stress, but it is a fact observed in many clinical settings that hair loss symptoms become more severe and recovery becomes slower as childbirth is repeated multiple times. So, does multiple births really increase the risk of hair loss in women? Several studies and clinical reports say yes.

1. Repeated childbirth leaves a ‘burden’ on our bodies

The changes that one birth leaves on our body and the changes that two or three births leave behind are different in depth and weight. The impact of fertility on hair loss can be explained by two key factors: ‘repetitive physical exhaustion’ and ‘lack of recovery time’.

Cumulative iron deficiency

Pregnancy, childbirth, and breastfeeding significantly deplete a woman's body iron stores. If you become pregnant and give birth to a second or third child in succession while your iron levels have not fully recovered after giving birth to your first child, it is very easy for your body to fall into a state of chronic iron deficiency. Iron is a key component of hemoglobin, which transports oxygen in the blood, and plays a role in supplying oxygen to hair follicles. Chronic iron deficiency is a direct cause of slowed hair growth and hair loss. (Source: Journal of Korean Medical Science and many other studies have reported that the higher the number of pregnancies (high parity), the significantly higher the prevalence of anemia and iron deficiency in pregnant women. This acts as an important risk factor for postpartum hair loss.)

repetitive hormonal shocks

The process of female hormones rapidly increasing during pregnancy and then plummeting after childbirth has a major impact on the hair. If we experience such drastic hormonal changes multiple times within a short period of time, our body's hormonal regulation system and hair follicle growth cycle do not have enough time to return to normal. This reduces hair follicle recovery and causes hair loss to become more severe or last longer. (Source: A study published in the International Journal of Dermatology suggests that women who have had more children may be more likely to experience telogen effluvium.)

Increased physical and mental stress

Raising one child is very stressful, but caring for two or three at the same time can completely drain a mother's physical and mental energy. Severe lack of sleep and stress keep levels of the stress hormone 'cortisol' chronically high, which shortens the hair growth period and promotes inflammatory reactions, acting as a strong factor in worsening hair loss. (Source: Several stress-related medical studies commonly point out that chronic stress causes and worsens Telogen Effluvium, and raising multiple children is considered one of the representative chronic stress factors.)

Ultimately, as we become more prolific, our bodies repeatedly experience the burden of nutritional depletion, hormonal shock, and stress without fully recovering. As these ‘burdens’ continue to pile up, postpartum hair loss becomes more intense, the recovery period becomes longer, and the risk of hair loss increases.

2. Why active recovery treatment is necessary

As such, fertility is an important risk factor for hair loss in women. Therefore, especially if women who have given birth multiple times experience hair loss symptoms, they should be more proactive in managing hair loss and scalp after giving birth rather than thinking, “It will get better with time.” It is also important to help the body's fundamental recovery through expert diagnosis and treatment.

For postpartum hair loss, I provide treatments that restore the body's fundamental strength that was depleted during pregnancy and childbirth. In Korea, there has long been a wise tradition of taking 'postpartum tonics' within 1 to 2 months after giving birth to replenish the mother's energy and blood and relieve stagnant blood. This was a process that went beyond simply restoring the body, to preparing for the next pregnancy and laying the foundation for long-term women's health.

My practice is also rooted in this tradition. Through internal and external medicines made entirely of natural ingredients, it restores weakened physical strength, stimulates metabolism, and helps ensure that nutrients are delivered to the hair follicles. At the same time, it improves scalp inflammation and promotes blood circulation, creating the optimal 'soil' for new hair to grow healthily.

The more births we have, the more attention and effort our bodies need for recovery. Don't take for granted the hair loss that comes after repeated childbirth. This could be a desperate signal from your body. When you replenish your depleted body and regain a healthy balance through active treatment, your hair can return to full and beautiful hair.
