Cold-pressed castor oil applied nightly to eyebrows, lash line, hairline edges, and scalp. Rich in ricinoleic acid, it penetrates the hair follicle to nourish and potentially stimulate growth. It conditions existing hair to reduce breakage, visibly thickens sparse brows within weeks, and is inexpensive enough to use generously everywhere.

Brows went from over-plucked and thin to full in 8 weeks. Only used castor oil nightly.

Edges and hairline filled in noticeably. It's messy but effective.
