How long to regrow hair?

How long did it take for your hairline vellus hair to transition to terminal hairs? I’ve had vellus hairs in my temples and about a half inch from my hairline back for probably about 6 months or longer now, and they’re SLOWLY getting longer, but they all still definitely in the vellus stage, being about 1/3rd of an inch long. I’m about 1 year total into my treatment of RU, Min, Fin, Microneedling, Ketoconazole shampoo, Essential Oils + Scalp Massages and inversion therapy.

So far I’ve gone from maybe a NW6 to a 4, but I’ve got decent coverage from my mid scalp to my vertex and vellus hair everywhere just short of my hairline up front. I’m getting a little impatient and perhaps a little worried they wont transition.

Everyone responds differently. The more advanced patterns of balding (class 6) may not be as responsive as the early patterns of balding (class 3) regardless of age.
