Tretinoin Is Causing Me to Grow a Unibrow

Hello Dr. Rassman and contributors,

I am almost positive that tretinoin increases hair growth, at least on the face. I have never had unibrow in my life but i can grow one in a week by applying tretinoin there, and it stops growing if i stop applying. My eyebrows can also grow higher and further along the temples when applied. I have done this many many times. I was thinking since tretinoin in part possibly works by preventing hyperkeritinization that hyperkeritinization could be synergetic in balding by allowing to DHT to “stay” longer in the follicle. Also I am very certain for me that it increases eyebrow growth, however I would be very skeptical, and would not try it on my head, are their different factors that influence hair growth on eyebrows vs scalp?

Thank You

I will assume that you are not experimenting on yourself because you are trying to grow a unibrow, but if you noticed that hair grew between your eyebrows when you used the medication, it makes sense that this could be a side effect. What else can I say?

Tretinoin (also known as Retin-A) has been said to cause hair loss for some people and grow hair for others.
