Can Hair Reverse Miniaturization During a Life Cycle?

You often talk of shedding and how in theory if miniaturized hairs are shedding after starting medication like Propecia it might be making way for new thicker hair. Is this the only way that reversing miniaturization can occur or can it happen within the same cycle? A reverse “exclamation point hair” I guess. Thin at the end and thick at the root.

Considering that most people have a hair cycle of 3 years and we see changes in miniaturization with medications in months, the answer is that changes do occur within cycles. I have the means to measure hair shaft thickness and maybe on a patient with an 8 month reversal of miniaturized hairs, I will measure the two ends of a single hair shaft.
