Pregnancy And Hair Growth: Why It Happens

what makes your hair and nails grow during pregnancy

Pregnancy brings about many changes in a woman's body, including changes to hair and nails. While some of these changes may be welcome, others may be less so. Many women notice that their hair and nails grow faster during pregnancy, and their hair may appear thicker and shinier. These changes are caused by hormonal shifts, increased blood flow, and metabolic changes that bring more nutrients to the hair and nails. However, the same hormonal changes can also cause unwanted hair growth in places like the face, belly, chest, and arms. Fortunately, most changes are temporary and resolve within a few months after delivery.

Hormonal changes during pregnancy cause hair growth

A woman's body undergoes several changes during pregnancy, and hair and nail growth are no exceptions. Many of these changes are due to swings in hormone levels. While some women may notice differences in their hair and nails, others may not.

Hormonal changes during pregnancy can also affect nail growth. Nails may grow faster and become harder. However, some women experience weaker, more brittle nails prone to splitting or breaking.

Temporary changes

It is important to note that these changes in hair and nail growth during pregnancy are temporary. After childbirth, hormone levels decrease, leading to a return to the previous growth cycles. Postpartum hair loss is a normal process, and hair and nail growth should return to normal within six months after delivery.

Hair texture changes are common during pregnancy

A woman's body goes through many changes during pregnancy, and hair texture changes are common. These changes are due to swings in hormone levels. Typically, about 85% to 90% of hair is growing, while the remaining 10% to 15% is in a resting phase before shedding. However, during pregnancy, hormonal changes prolong the growth phase, resulting in less shedding and thicker hair.

Pregnancy hormones can also cause hair texture changes, making hair drier, oilier, frizzier, or even altering its curl pattern. For example, curly hair might become straighter. These changes are more noticeable in women with longer hair. Additionally, hair may grow in new places, such as the face, chest, belly, and arms, due to increased androgens, estrogen, human chorionic gonadotropin, progesterone, prolactin, growth factors, and cytokines.

While some women embrace the changes in their hair texture during pregnancy, others may find it frustrating. It's important to remember that these changes are temporary and usually resolve within six months after giving birth. To manage hair texture changes during pregnancy, some women opt for different hair care products, such as shampoos and serums that lock in moisture. Consulting a dermatologist or a trusted healthcare provider can also provide personalized advice and recommendations.

After pregnancy, it is common to experience postpartum hair loss as hormone levels decrease and the growth cycle returns to its previous pattern. This typically occurs around three to four months after delivery and can be addressed by focusing on a nutrient-rich diet and gentle hair care practices.

Nails grow faster but become brittle

During pregnancy, your body undergoes hormonal and physiological changes that can affect your hair and nails. While some women notice positive changes, such as thicker and shinier hair, others may experience less desirable changes, such as nails growing faster but becoming more brittle.

Hormonal changes during pregnancy, specifically increased estrogen levels, can prolong the growth phase of nails, resulting in faster nail growth. However, these same hormones can also make nails weaker and more brittle, prone to splitting or breaking. This is a common occurrence during pregnancy, but it can also indicate an iron deficiency, so it is important to consult a healthcare provider if you are concerned.

To maintain nail health during pregnancy, it is recommended to protect nails by wearing rubber gloves when doing tasks that involve water or chemicals, such as washing dishes or cleaning. Proper nutrition is also crucial, including ensuring adequate calcium and biotin intake. Biotin, a B-complex vitamin, can improve nail firmness and hardness and is found in foods like nuts, eggs, oatmeal, spinach, broccoli, bananas, and whole grains. Additionally, regular moisturising with hand creams or oils can help keep nails hydrated and reduce breakage. Keeping nails trimmed and filed can also prevent snags and breakages.

While nail changes during pregnancy are normal and temporary, resolving within months after delivery, it is always advisable to consult a healthcare professional if you notice any unusual symptoms or have any concerns about your nail health.

Pregnancy vitamins may affect hair and nail growth

Pregnancy is a time of significant hormonal and physiological changes in a woman's body, which can lead to various noticeable differences, including changes in hair and nail growth. While the exact mechanisms are not fully understood, it is believed that these changes are primarily driven by shifts in hormone levels, particularly an increase in estrogen and androgens. Additionally, prenatal vitamins and increased blood circulation may also contribute to hair and nail growth during pregnancy.

During pregnancy, many women experience thicker and fuller hair. This is due to higher estrogen levels, which prolong the growth phase of the hair cycle, resulting in reduced shedding and a fuller appearance. The increased levels of estrogen also cause hair to remain in the resting phase for a longer duration, further contributing to the perception of thicker hair. It is important to note that while individual hair strands do not become thicker, the decreased shedding leads to an overall increase in hair volume.

In addition to changes in hair thickness, some women may notice alterations in hair texture. Pregnancy hormones can make hair drier, oilier, or change its curl pattern. For example, curly hair might become straighter. These changes in texture can be managed with specific hair care products, such as shampoos and serums that lock in moisture. It is recommended to opt for fragrance-free products and those specifically designed for pregnant women to avoid harsh chemicals.

Pregnancy can also influence nail growth and strength. Some women experience faster nail growth, while others may find their nails becoming weaker, more brittle, and prone to splitting or breaking. The increase in hormones, along with the extra intake of folate and biotin from prenatal vitamins, are believed to contribute to these changes in nail growth and strength. To maintain nail health during pregnancy, it is recommended to moisturize regularly, file gently, and include biotin, protein, and iron in the diet.

While the changes in hair and nail growth during pregnancy are temporary, they can be noticeable and sometimes frustrating for expectant mothers. It is important to prioritize overall health and consult healthcare professionals for personalized advice. Maintaining a gentle hair and nail care routine, using pregnancy-safe products, and incorporating nutrient-rich foods into the diet can help manage these changes effectively.

Postpartum hair loss is normal

During pregnancy, higher levels of estrogen prolong the growth phase of the hair cycle, resulting in less shedding and thicker hair. However, after giving birth, estrogen levels drop, causing hair to enter the resting phase of growth. A few months later, this hair starts to shed, resulting in postpartum hair loss.

Postpartum hair loss is a normal and very common part of pregnancy and childbirth, affecting over 90% of women. It typically begins around 2 to 5 months after delivery and lasts for about 6 months to 1 year. During this time, it is normal to lose more than 100 hairs per day, which is more than the typical daily shedding of 50 to 100 strands. While it may be distressing to experience hair loss, it is important to remember that it is only temporary and new hair will start growing back as soon as the old hair falls out. By your baby's first birthday, your hair should be full again.

There is currently no treatment for postpartum hair loss, and it cannot be prevented. However, certain steps can be taken to help hair feel fuller and prevent further hair loss and damage. This includes using volumizing shampoos and lighter conditioners, as well as focusing on a nutrient-rich diet and gentle hair care.

While postpartum hair loss is normal, it is important to consult a healthcare provider if you experience severe hair loss or if the hair loss persists for more than six months, as it may be a sign of another condition such as iron deficiency or thyroid disease.

In addition to hair changes, it is common to experience nail alterations during pregnancy. Nails may grow faster, become brittle, and be more prone to splitting or breaking. These changes are also due to hormonal shifts, and nail strength and texture typically improve after giving birth. To maintain nail health during pregnancy, it is recommended to moisturize regularly, file gently, and include biotin, protein, and iron in the diet.
