Yes, like natural hair, transplanted hairs may thin slightly with age, though they remain much more resistant to balding. Since they are harvested from genetically stable donor zones, they are not as vulnerable to hormonal factors that cause hair loss. This means most transplanted hairs last a lifetime. Advanced extraction methods like UFME help preserve graft health, while DSHI ensures each follicle is securely placed for natural, long-term growth. Regular scalp care, a balanced lifestyle, and follow-up treatments such as PRP therapy can help maintain thickness and maximize the longevity of results.
