Great question! Seborrheic dermatitis itself doesn't directly cause acne, but the two conditions can show up at the same time. They share some common triggers, like excess oil production, stress, and hormonal changes, which can make both more likely to occur together.

Great question! Seborrheic dermatitis itself doesn't directly cause acne, but the two conditions can show up at the same time. They share some common triggers, like excess oil production, stress, and hormonal changes, which can make both more likely to occur together.

Seborrheic dermatitis tends to appear in oilier areas of the body, which can include the upper back — so it's possible what you're seeing on your back or shoulders could be seborrheic dermatitis rather than acne, or even both. As for long hair specifically, it's worth considering that hair can transfer oils, product residue, or yeast to the skin on your back and shoulders, which could potentially aggravate either condition.

The best way to know for sure what's going on is to check in with a dermatologist, who can tell the difference and help put together the right treatment plan for you.
