Thinning Eyebrows After 50: Check the Cause Before Microblading

Sparse brows are a common complaint after 50, and microblading or permanent brow makeup promises a fuller look that lasts. Before you book, it’s worth knowing why brows thin and what the ink involves.

Brow loss can be a medical sign

Frontal fibrosing alopecia (FFA) is a scarring hair loss that mainly affects women after menopause. It starts after menopause in about 83% to 95% of women who get it, and cases have been rising worldwide.¹

• Eyebrow loss shows up in about 63% to 83% of people with FFA.¹
• It can start at the outer third of the brow or as overall thinning.¹
• In more than a third of cases, brow loss comes before the hairline starts to recede, and sometimes it’s the only sign.¹

Because FFA scars hair follicles, early diagnosis matters. The review notes some treatments seem promising for slowing it.¹ Our article on lichen planopilaris follow-up covers a related condition. Other causes of brow thinning include thyroid problems and overplucking; our guide to thinning hair explains how clinicians sort out causes.

What to know about the ink

The FDA² treats permanent makeup inks as cosmetics, and none of the color additives is approved for injection into the skin.² The practice itself is regulated locally.² Risks the FDA lists include:²

• Infection from unsterile equipment or contaminated ink
• Allergic reactions, sometimes years later
• Granulomas (bumps) and keloid scars
• Hard removal: complete removal without scarring may be impossible
• Changing looks: permanent makeup may later clash with changing skin tone and facial contours

In 2003 and 2004, the FDA² received more than 150 reports of reactions to certain permanent makeup ink shades.² Tattooed brows rarely cause problems in an MRI, but tell the radiology team.² Our article on MRI and permanent makeup explains.

Checklist before microblading

1. See a dermatologist if brows are thinning without an obvious reason, especially with hairline changes.
2. Check your local license rules for the studio.²
3. Ask about sterile, single-use needles and unopened ink.
4. Ask for a patch test if you have sensitive skin.
5. Choose softer, natural shades that will age well.
6. Try brow pencils or powders first to test shape and color.

Try: “My eyebrows have thinned a lot since menopause and my hairline looks higher. Could this be frontal fibrosing alopecia, and should I wait before microblading?”

Hair, Everywhere includes a Hair Check, a monthly Hair Log and a visit script. Use them to photograph your brows and hairline each month and bring them to your appointment. See the book.
