NEW YORK, July 9: New York City-based, Harvard-educated dermatologist Dr. Charles Puza has shared his top recommendations for maintaining healthy hair. In a TikTok video last month, Puza emphasized the importance of rotating shampoos, using a blow-dryer on a cold setting, and incorporating hair masks into your routine.

1. Rotate Your Shampoos
   Puza advises against using the same shampoo every day. Much like skincare, hair care needs can change, requiring different products for optimal health. He suggests a technique called hair cycling, which involves rotating shampoos to address various scalp conditions. For instance, a ketoconazole shampoo can target Malassezia fungus, a primary cause of dandruff, while a selenium and salicylic acid shampoo can reduce both visible and invisible dandruff. “Even background dandruff is bad for your hair,” Puza noted. This method is supported by Healthline Media’s clinical adviser, Dr. Meredith Goodwin, who explained that changing shampoo and conditioner combinations can improve the feel of hair by preventing buildup on the hair shaft.
2. Avoid Air-Drying Your Hair
   Contrary to popular belief, air-drying hair is not recommended by Puza. He insists that allowing hair to remain wet for too long can be damaging. Instead, he advocates using a blow-dryer on the cold setting, which he considers the healthiest way to dry damp hair. Additionally, brushing wet hair should be avoided as it can cause strands to stretch and break. Senior hair stylist Bronwen Robinson from Suite Caroline in Soho compared wet hair to “wet spaghetti,” recommending the use of a natural fiber brush to detangle hair before it gets wet.
3. Incorporate Leave-In Conditioner
   For the best hair care, Puza suggests a weekly ritual of using leave-in conditioner. He compares this to giving skin a peel and exfoliation, highlighting the benefits of concentrated TLC for hair. “These hair masks are a game-changer,” Puza stated.

By following these tips, you can improve the health and appearance of your hair, ensuring it remains strong and vibrant.
