Studies show that restoring hair follicle stem cell activity is the key to reversing thinning and promoting natural regrowth. Proper cellular rejuvenation supports stronger roots, thicker strands, and a balanced scalp environment. As we age, stress, hormonal shifts, and environmental damage weaken follicle function — slowing regeneration and increasing shedding.
By reactivating dormant follicle stem cells and improving scalp microcirculation, it’s possible to restore the hair’s growth cycle, enhance density, and strengthen each strand from the root up.

Shocking hair loss statistics include the high prevalence, with up to 85% of men and 50% of women experiencing hair loss at some point. Many men see symptoms in their 20s, and by age 50, 50% of men will have some degree of hair loss. Statistically, 25% of men who experience hair loss start seeing signs before age 21, and a significant number of women (around 40%) can expect to experience hair loss by the time they reach menopause.
Month 1:
Early changes begin. Follicles start reactivating as shedding slows and skin feels calmer. Fine baby hairs become visible along sparse brow tails and thinning edges.
Month 2:
New growth becomes more noticeable. Brows look denser, and gaps start filling in naturally.
Month 3:
Visible transformation. Brows appear fuller, more even, and easier to shape. With consistent use, Castéa helps strengthen new strands and maintain healthy regrowth long-term.
Month 4+:
Sustained results. Follicles remain active, thicker and stronger look — without the heavy makeup, oils, or irritation.
Results may vary, but most users report visible regrowth within 6–8 weeks of consistent use.
