Let's clear up some myths about scalp health!
★ THE SCIENCE
Seborrheic dermatitis is the medical term for "dandruff." It's a chronic skin condition that often affects the scalp, causing itching, flaking, redness, and sometimes even hair shedding.
★ FAKE NEWS
Traditionally, ads have referred to this as "dry scalp" due to the flakes seen. This, however, is a MISNOMER. The flakes are actually greasy scales produced by oil gland-rich parts of the skin, such as the scalp.
★ ROOT CAUSES (pun intended)
Genetics, hormones, stress, poor sleep habits, and an overgrowth of yeast called Malassezia may play a role in who is prone to dandruff. In some cases, it may be associated with psoriasis or acne.
★ DETRIMENTAL SOCIAL MEDIA TRENDS
"Scalp training," AKA washing the hair less often to supposedly train your hair to produce less oil over time. In reality, this only leads to more oil and dead skin build-up—fuel for dandruff-causing yeast overgrowth.
Scalp oils? No thanks.
Your scalp naturally produces oil. Add heavy scalp oils on top, and you’re basically sending an RSVP
to buildup, clogged follicles, and yep—dandruff.
★ DANDRUFF HAIR CARE TIPS
Wash more, not less! There’s no one-size-fits all to how often you should shampoo, but if you're flaking, you actually need to wash more often and with the right ingredients (like zinc pyrithione).
★ PRODUCT RECOMMENDATION
Dr. McCall's new favorite OTC dandruff remedy is Jupiter Anti-dandruff Balancing Shampoo because it's tough on flakes but soft on strands.
