Still air-drying your hair? Blow-drying might actually be better for your scalp

After stepping out of the shower, it’s tempting to leave your hair to air-dry, especially if you're trying to avoid heat damage.

But did you know that blow-drying your hair might actually be better for your scalp under certain conditions? While it sounds counterintuitive, letting your scalp stay damp for too long could potentially lead to problems.

The question then arises -- can blow-drying be a healthier habit when done right? Does it help prevent scalp irritation or infection? And what’s the right way to do it if you want to avoid damage? These are the questions that come up often but rarely get clear answers. (Source: Freepik)

Increased risk of fungal infections, dandruff, or irritation

Dr Bhavuk Dhir, Consultant dermatology at PSRI Hospital, tells indianexpress.com, “Yes, leaving your scalp damp for a prolonged period after a shower can increase the risk of fungal infections, dandruff, and scalp irritation. A moist and warm environment creates a perfect breeding ground for fungi and bacteria, especially Malassezia, a type of yeast that naturally lives on the scalp but can overgrow and lead to dandruff when moisture is trapped.” (Source: Freepik)

Additionally, he notes that excess dampness “weakens the scalp’s natural barrier, potentially causing itching, irritation, or even scalp acne.” Therefore, drying your hair and scalp properly after washing is not just about appearance -- it's important for maintaining good scalp hygiene and preventing skin-related issues.

How to go about it

Dr Dhir says, “Blow-drying your hair using a low or medium heat setting can actually be healthier for your scalp than letting your hair air-dry completely. While I believe air-drying is the gentlest option, keeping the scalp damp for too long -- as often happens with air-drying -- can lead to problems like microbial overgrowth and irritation. Controlled blow-drying, especially when done from a distance of 6-8 inches and with constant movement, helps remove excess moisture without overheating or damaging the scalp.”

He adds that high heat settings “should be avoided, as they can dry out and inflame the scalp.” Blow drying should be done at normal temperature only. Therefore, when done mindfully, blow-drying on lower settings is a safer and more hygienic alternative. (Source: Freepik)

Protecting both scalp health and hair quality

The safest and most effective way to dry your hair after a shower involves a combination of gentle towel-drying and controlled blow-drying and avoiding combing wet hairs, says Dr Dhir. He provides a step-by-step guide. (Source: Unsplash)

“First, use a soft microfiber towel or cotton T-shirt to gently squeeze out excess water without rubbing the scalp or hair, as aggressive towel-drying can cause breakage and irritate the scalp. Allow your hair to air-dry partially -- about 60-70% -- and then finish drying with a blow dryer on low to medium heat, keeping it at a safe distance from the scalp. Using a heat protectant spray can further protect hair strands. This method balances moisture control, protects scalp health, and maintains hair strength and shine,” concludes Dr Dhir.
