Hair Loss

• About 40% of women experience noticeable hair loss by the age of 40.
• Hair loss can occur at any age, but it's more common as women approach menopause, typically between the ages of 45 and 55.
• Genetics play a significant role in female pattern baldness. If your mother or grandmother experienced hair loss, you may be more susceptible.

Types of Hair Loss
There are several different types of hair loss that occur in women - knowing which type is important so the right treatment and prevention steps can be taken.

Female Pattern Hair Loss (Androgenetic Alopecia)
This is the most common cause of hair loss in women, affecting an estimated 30 million women in the United States alone. It typically begins after menopause, but it can start at any age, with the risk increasing as women get older.

Telogen Effluvium
This type of hair loss is characterized by excessive shedding of hair due to stress, illness, medication, or hormonal changes. It can affect women of all ages, and it often resolves once the underlying cause is addressed. This is an extremely common form of hair loss in women!

Postpartum Hair Loss
Many women experience postpartum hair loss in the months following childbirth; about 40-50% of women notice significant hair loss in the months after giving birth.This is typically temporary and the lost hair is regrown with a few months.

Aging-related hair loss
By the age of 50, nearly half of all women will have some degree of hair loss or thinning.

Alopecia Areata
This is an autoimmune condition where the immune system attacks the hair follicles. This can happen in both men and women (women account for about 40% of alopecia areata cases.) It can occur at any age and can show up in a variety of ways from dime-sized “bald spots” to entire hair loss all over the body.

Ethnic and Racial Differences
Women of African, Asian, and Hispanic descent may have a lower risk of androgenetic alopecia compared to women of European descent.

 Why Does It Happen?

In general, hair loss in women can be attributed to 3 main issues:

1. Nutritional Deficiencies: Inadequate intake of essential nutrients, such as iron, biotin, and protein, can weaken hair follicles.

2. Stress: High-stress levels can lead to a condition called telogen effluvium, where hair prematurely enters the resting phase and falls out.

3. Hormonal Changes: Fluctuations in hormones, such as those during pregnancy, perimenopause, menopause, or thyroid disorders, can contribute to hair loss.

Nutrition-Specific Tips for Hair Loss in Women:

The relationship between nutrition and hair loss in women is significant. Adequate nutrition plays a crucial role in maintaining healthy hair, and deficiencies in certain nutrients can contribute to hair thinning and loss. Here are some specifics about how nutrition impacts hair health in women:

Protein
Hair is primarily composed of a protein called keratin. A deficiency in protein can lead to weaker, more brittle hair and may contribute to hair loss. Ensure you have an adequate intake of protein rich foods, whether you’re an omnivore, vegetarian or vegan. We have a video on how different types of protein are absorbed, here.

Iron
Iron deficiency, often referred to as anemia, is an extremely common cause of hair loss in women. Iron is essential for the production of hemoglobin, which carries oxygen to the hair follicles. When follicles don't receive enough oxygen, hair growth is affected. Incorporate iron-rich foods like red meat, beans, lentils, spinach, and fortified cereals into your diet. Also, it’s a good idea to get a blood test to see what your iron levels are. If you’re low, it’s ok to supplement with iron.

Collagen
Collagen is the protein that provides structural support to hair. Collagen supplements or foods like bone broth may help improve hair health.

Biotin
Biotin plays a role in strengthening hair and preventing breakage. Biotin is also known as vitamin H or B7. The "H" in vitamin H stands for "Haar und Haut", which is German for "hair and skin”!  Biotin should be supplemented with other B vitamins (B vitamins work synergistically together). It's found in foods like eggs, nuts, seeds, and whole grains.

Omega-3 fats
Among the many benefits of Omega-3 fatty acids, they have are helpful for growing hair and restoring thickness. They can help reduce inflammation in the scalp and promote healthy hair growth. Omega-3’s are one supplement that everyone should have in their vitamin cabinet! They’re also found in fatty fish (like salmon and mackerel), flaxseeds, and walnuts.

Vitamin A Deficiency of this vitamin can lead to dry and brittle hair. Foods rich in vitamin A include sweet potatoes, carrots, and leafy greens.

Vitamin C is necessary for the organization of collagen to create the structure of hair.  Citrus fruits, strawberries, and bell peppers are excellent sources of vitamin C.

Vitamin E is an antioxidant vitamin that helps improve blood circulation to the scalp. You can find vitamin E in nuts and seeds.

Zinc deficiency is associated with hair loss. Foods rich in zinc include oysters, lean meats, whole grains, and legumes.

Hormones

Hormonal imbalances can play a significant role in female hair loss. Hormones are essential chemical messengers in the body, and changes in hormone levels can affect various bodily functions, including hair growth and loss. Here's how hormonal imbalances can contribute to female hair loss:

Androgens (Male Hormones)
Androgens are a group of hormones that include testosterone and dihydrotestosterone (DHT). While both men and women have these hormones, women typically have lower levels. In some cases, women may experience an increase in androgen levels, which can lead to hair loss. Elevated androgens can cause hair follicles to shrink and produce thinner, shorter hair, ultimately leading to hair thinning and loss.

Polycystic Ovary Syndrome (PCOS)
PCOS is a common hormonal disorder in women that can lead to excess androgens and blood sugar dysregulation. Women with PCOS often experience symptoms such as irregular menstrual periods, acne, and increased hair growth (hirsutism) on the face and body. Hair loss, particularly at the crown of the head, is another potential symptom of PCOS.

Menopause
Hormonal changes during menopause, specifically a decrease in estrogen levels, can lead to hair thinning and loss in many women. Estrogen has a protective effect on hair follicles, so its decline can make hair more susceptible to the effects of androgens.

Thyroid Hormones
Thyroid hormones, including thyroxine (T4) and triiodothyronine (T3), play a crucial role in regulating metabolism. An underactive thyroid (hypothyroidism) or an overactive thyroid (hyperthyroidism - "Hashimoto’s Disease & Graves' Disease") can disrupt the normal hair growth cycle and lead to hair loss. Treating the underlying thyroid condition can often help resolve the hair loss issue.

Stress Hormones
Chronic stress can lead to an imbalance in stress-related hormones such as cortisol. Elevated cortisol levels can disrupt the hair growth cycle and lead to hair shedding or hair thinning. 

Birth Control Pills
Hormone birth control methods, including certain oral contraceptives, can affect hormone levels in women. Some women may experience hair thinning or hair loss as a side effect of these medications. Changing to a different contraceptive method or formulation may help alleviate this issue.

Measuring hormone levels using a saliva test can reveal if hair loss is due to an underlying hormone imbalance.

Hair loss in women is a common concern that can be caused by various factors, including hormonal changes, stress, and nutritional deficiencies. While complete prevention may not always be possible, maintaining a balanced diet, managing stress, and using natural remedies can help improve hair health and reduce the risk of hair loss. If hair loss is severe or persistent, it's essential to consult a healthcare professional for a proper diagnosis and treatment plan tailored to your specific needs.
