The 90-day hair recovery timeline
Hair grows in cycles. Whatever you do today shows up in your mirror in roughly three months. That means consistency beats intensity — and gives you a clear "is this working?" check-in at week 12.
- Weeks 0–4: Shedding may continue or briefly worsen as old hairs are pushed out by new growth.
- Weeks 4–12: Shedding slows. Baby hairs at the parting (1–3 cm) are the first visible win.
- Months 3–6: Density increases noticeably. Most women see meaningful regrowth by month 6.
The fundamentals that move the needle
- Get ferritin above 70 ng/ml. Bigger lever than any shampoo.
- Eat 1.6–2.0 g protein / kg / day. Hair is keratin — built from the protein you ate yesterday.
- Stop fasted long workouts and aggressive deficits. Both spike cortisol and shed hair.
- Consider 5% minoxidil daily. The only over-the-counter regrower with strong evidence.
- Discuss HRT or spironolactone with your GP. Both address the root cause for the right candidate.
