No, you cannot take ANY supplement containing vitamin A. If you can find a multivitamin supplement that doesn’t control Vit A, or betacarotene then its fine. Question any pharmacist for a supplement like that.

As a substitution for of taking a prenatal vitamin, which will doubtless give you a lot of material that you in fact don’t need, I would urge a manufactured commodities with Biotin that is designed to support healthful hair. I suspect that is the ingredient in prenatal vitamins that makes them so excellent for hair.
In the meantime, make sure you are by a moisturizing clean and conditioner. I know a lot of us with acne prone skin also suffer from an oily scalp and hair, so moisturizing clean is ordinarily not something we have around the house. It in fact does make a alteration.
And of course, talk to your dermatologist. You can also call their office and talk to a personnel limb in between appointments. They’ve heard it all and can be a in fact excellent pile. (Beyond doubt more reliable in rank than most of the posters here at Y!A.)
Excellent luck!! :]
