Hormones and hair: A complex relationship
Hormones play a crucial role in the health and growth of our hair – and therefore also our scalp. In particular, androgens (male hormones, which are also present in small amounts in women), estrogens, and thyroid hormones can have a significant impact. These hormonal fluctuations are especially noticeable in Afro-textured hair and curly hair, whose follicle structure can be particularly sensitive to changes.
Hormonal changes can manifest themselves in various ways:
-
Hair loss: An imbalance (e.g., elevated androgen levels, thyroid dysfunction) can lead to hair loss, often noticeable as thinning or increased hair loss.
-
Altered sebum production: Hormones influence the activity of the sebaceous glands. An excess of androgens can lead to increased sebum production, resulting in an oily scalp and dandruff. A deficiency can lead to dryness.
-
Changes in hair structure: In rare cases, hormonal changes can also affect the texture of the hair.
-
Scalp sensitivity: Hormonal fluctuations can make the scalp more sensitive and lead to itching or irritation.
Typical phases of hormonal changes are:
-
Puberty: Wildly fluctuating hormones can lead to oily scalp or acne.
-
Pregnancy: Many women experience thicker, shinier hair, followed by postpartum hair loss.
-
Menstrual cycle: Slight fluctuations in sebum production or sensitivity may occur.
-
Menopause: The decline in estrogen can lead to thinner hair and a drier scalp.
-
Thyroid dysfunction: Both over- and under-thyroidism can cause hair loss and changes in the condition of the hair and scalp.
-
PCOS (Polycystic Ovary Syndrome): Can lead to increased hair growth in unwanted areas and hair loss on the scalp, often accompanied by an oilier scalp.
Strategies to support your scalp during hormonal changes
While hormonal causes often require medical evaluation, you can support your scalp and hair with targeted care:
-
Professional medical assessment:
-
If you experience noticeable hair loss, significant changes to your scalp, or other symptoms that might indicate a hormonal imbalance, you should definitely consult a doctor or endocrinologist . A blood test can provide answers, and medication may be necessary.
-
-
Customized hair care routine:
-
Gentle cleansing: Use sulfate-free, pH-neutral shampoos that are tailored to your scalp's needs (e.g., for dry or oily scalp). This helps maintain the scalp's natural barrier function.
-
Targeted scalp care:
-
For oily scalp: Use clarifying serums or tonics with ingredients such as tea tree oil or salicylic acid, which can regulate sebum production.
-
For dry/sensitive scalp: Use moisturizing oils (jojoba, argan) or serums with hyaluronic acid to soothe and moisturize the scalp.
-
-
Avoid harsh products: Chemical treatments like relaxers or dyes can further stress a scalp already sensitized by hormones. Reduce their use or choose gentler alternatives.
-
-
Stimulate hair growth (supportive):
-
Some products and ingredients can stimulate hair growth by improving blood circulation to the scalp or strengthening the follicles. These include caffeine, rosemary oil, and biotin . Keep in mind that this only provides support and does not address any underlying hormonal causes.
-
-
Healthy lifestyle:
-
Balanced diet: A nutrient-rich diet with sufficient protein, vitamins (especially B vitamins, vitamin D) and minerals (iron, zinc) is crucial for healthy hair growth.
-
Stress management: Chronic stress affects the hormonal system. Stress reduction techniques (yoga, meditation, exercise) can have a positive effect.
-
Sufficient sleep: Restful sleep supports the regeneration of the body and the hormonal system.
-
-
Patience:
-
Changes in hair growth and scalp condition due to hormones are often long-term. Be patient and consistent with your hair care routine and lifestyle changes.
-
Hormonal influences on the scalp are complex, but with the right knowledge and appropriate support you can optimally promote the health of your Afro hair and curls.
