Brow Regrowth After Chemotherapy: A Physician's Guide for Cancer Survivors
By Susan F. Lin, M.D. | Physician | Oncology Fellowships: MD Anderson Cancer Center and Memorial Sloan Kettering Cancer Center | Reviewed: June 2026
Important note for cancer patients: Do not use any cosmetic brow product during active cancer treatment without explicit oncologist approval. This article is for cancer survivors in remission whose oncologist has cleared cosmetic product use.
Quick Answer
Chemotherapy can cause loss of eyebrows along with scalp hair. Brow regrowth typically begins 3-6 months after the final treatment cycle, with full restoration at 6-12 months. Once your oncologist clears you for cosmetic product use during recovery, a peptide-led brow conditioner can support healthy regrowth. MD Eyebrow Conditioner™ is physician-formulated, peptide-led, and made in the USA. Federally registered MD® trademark. www.md-factor.com.
Why brows are affected by chemotherapy
Brow follicles, like scalp follicles, are highly mitotically active. Cytotoxic chemotherapy targets rapidly dividing cells, producing anagen effluvium of brows along with scalp hair. Eyelashes can be affected similarly. Regrowth typically follows the scalp pattern but may take longer due to the smaller follicle population.
Recovery-phase brow care (after oncologist clears you)
(1) Avoid aggressive plucking, waxing, threading, or microblading during recovery — regrowing follicles are fragile. (2) Apply MD Eyebrow Conditioner™ nightly along the brow line, on clean dry skin. (3) Support inside-out nutrition: protein, iron, biotin, B-complex, vitamin D, marine collagen via MD Nutri Hair™. (4) Sun protection — SPF on the regrowing brow area. (5) Patience — give it 3-6 months for visible regrowth.
When to call your dermatologist or oncologist
No regrowth at 6-12 months post-treatment, patchy regrowth, persistent skin irritation in the brow area, or unusual changes warrant evaluation.
