Eyebrow problems: causes, what helps, and what to skip
The right product depends on why brows are thin, patchy or uneven. Pick the problem that matches yours. Each page covers likely causes, what the evidence supports, and when to see a doctor.
Over-plucked or over-waxed brows
Follicles are usually intact but miniaturised. Stop shaping for 12 weeks; a peptide serum can shorten the wait.
Good outlook with serums → EndocrineThinning at the outer third
Symmetrical loss of the brow tail is a classic sign of hypothyroidism. A blood test comes before any product.
See a doctor first →Sudden patchy loss
Round, smooth bald patches suggest alopecia areata. Often regrows on its own; dermatologists can treat stubborn patches.
Medical treatmentThinning after menopause or pregnancy
Falling oestrogen shortens the growth phase. Serums tend to give weaker results in this group; patience and conditioning matter more.
Partial response to serumsFlaky, itchy or red brows
Seborrhoeic dermatitis, not dry skin. Oils make it worse. Antifungal shampoo on the brows usually resolves it.
Treat the skin, not the hair →Grey, coarse or wiry brow hairs
Normal with age. Trimming, tinting and a conditioning oil are the right tools; growth serums will not change texture.
