I looked up some side effects of Differin and hair loss is included among them. There are a couple Differin-related hair loss threads on this forum, but they don't have many replies.
The information that I have learned is that vitamin A toxicity can happen, since Differin and other retinoids are derivatives of vitamin A. However, hair loss is not listed on the package because it is not a confirmed side effect.
I am concerned: I don't think my acne is going away (I've been using Differin for a week), and I don't want to be bald or have thinning hair. I mean, isn't acne bad enough?
Did anyone experience loss or thinness of hair while using Differin? If so, was it permanent for you, or did it grow back after you stopped Differin? On the other hand, did anyone NOT experience any sort of hair loss side effect? Any other weird side effects of Differin you experienced? How about other retinoids?
As of right now, I'll keep using Differin, but I'm going to keep a close eye on my hair.
