Did your fitness glow up era skip your hair?

I am a very recent, somewhat reluctant convert to the world of fitness. When January 2026 rolled around, my resolution for the year was simple, even if clichéd—to get fit. For years, my relationship with exercise had been theoretical, but this time, I actually laced up my sneakers, bought matching activewear, and committed. When I first started, I fully expected this phase of the journey to be an obsession with the physical metrics—tracking muscle soreness, counting calories, and nervously eyeing my form in the Pilates studio mirrors. What I didn’t expect was to become utterly consumed by what was happening to my hair.

Blame it on my Instagram feed. For months, I watched fitness influencers crush deadlifts in pastel co-ords, hair pulled into a perfectly snatched Hailey Bieber bun—not a single strand out of place. Kendall Jenner walking out of a reformer class looking like an Alo Yoga ad, a silk scrunchie holding everything together as if gravity (and sweat) didn’t apply to her. I bought into it completely.

Bun voyage

Unless the paparazzi is waiting outside your West Hollywood Pilates studio, real sweat isn’t camera-ready. Our obsession with chasing the clean girl aesthetic—specifically those perfectly slicked-back buns we see all over our feeds—has completely warped our understanding of actual scalp hygiene. Instead, we’re either glueing it down with heavy gels or stripping it bare out of panic.

“Many people mistakenly believe that the scalp needs to be completely free of products before exercising. In fact, the objective is to establish conditions that reduce sweating, friction, and excessive microbial growth,” says Dr Priyanka Keshav, dermatologist, VLCC Group. So, what should you actually put on your hair before a workout? Less than you think. Layering up on heavy oils, thick leave-in conditioners, and styling gels right before a sweat session is a one-way ticket to a clogged scalp.

When those rich formulas mix with actual sweat, they create heavy debris that suffocates your hair follicles, leading to flare-ups of dandruff, scalp acne, and folliculitis. If you’re prone to an oily scalp, Dr Keshav suggests swapping the heavy stuff for a lightweight serum packed with niacinamide or caffeine to keep things balanced. “Dermatologically speaking, starting with minimal product residue is the healthiest approach before any physical activity,” she notes.

So, if we can’t channel that Sofia Richie high bun energy on the treadmill, should we switch to ponytails? While it relieves the root tension a tight bun creates, it trades one problem for another—the constant swinging introduces friction and whip-like trauma along the hair shaft, chipping away at the cuticle. “But the ponytail is still the lesser evil,” says Delhi-based cosmetic dermatologist and Isya Aesthetics founder, Dr Kiran Sethi. “A damaged shaft can be conditioned or trimmed. A dead follicle cannot be revived.” To protect your edges from early retirement, the move is to opt for a loose ponytail right at the base of your neck, or a soft braid.

But, before you grab whatever generic hair tie is rolling around the bottom of your gym bag, you need to match your accessory to your movement. Dr Keshav suggests that for high-intensity cardio, silk scrunchies—despite being low-friction—might not give you the grip you need to survive a burpee.

Pro tip: On high-impact days, reach for fabric-covered elastic ties instead. They keep your ponytail locked in place through even the toughest workout; no mid-session tugging required.

Sweat has a type

As it turns out, your scalp knows exactly what workout you did today, and it treats an intense Barry’s Bootcamp class differently than a reformer Pilates session.

When you’re crushing high-intensity cardio, your entire scalp and hair shaft become coated in an acidic, salty-sweat mix. Leaving sweat to dry on its own dehydrates the hair and can irritate the scalp. For this kind of all-over sweat, a post-workout rinse isn’t optional. At minimum, rinse with lukewarm water to wash out the salt, then go in with a gentle, sulphate-free shampoo on the scalp and a rich conditioner from mid-shaft down.

Pilates or a heavy lifting session, on the other hand, plays by different rules. You might not be dripping from your forehead, but sweat pools heavily at the back of your head and the nape of your neck—made worse by the constant friction of leaning against a reformer pad or weight bench. “This creates a trapped, hot, humid zone,” says Dr Sethi. “It becomes a breeding ground for fungal acne and seborrhoeic dermatitis because of the trapped moisture. If the rest of your hair is dry, don’t strip it with a full wash. You need a targeted strike just where the sweat pools.”

This is exactly where the art of spot-clean saves your hair (and your sanity). 

“Section your hair and wash only the nape of your neck,” advises Dr Sethi, “using a clarifying shampoo or a targeted rinse containing zinc pyrithione or salicylic acid to neutralise fungal bumps before they can even start.”

Pro tip: If the top of your head is dry, you don't actually need to wash your entire mane.

The mane plan

This brings up the recurring dilemma for anyone hitting the gym three to four days a week: How often is too often to wash? If you’re working out that often, you’ve definitely stared in the mirror playing a risky game of “is daily washing destroying my strands, or is letting this salty pool marinate for 48 hours actively worse?”

According to Dr Keshav, leaving sweat and sebum on your scalp for 48 hours usually creates more problems than washing correctly does. We’ve been blaming the wrong thing—the damage from daily washing actually comes from scrubbing too hard, using water that’s too hot, or blow drying right after, not the washing itself. When you work out regularly, scalp hygiene matters more than protecting your blowout. Let sweat and oil sit too long, and you’re looking at irritation, dandruff, and clogged follicles. While the exact wash frequency depends on your specific hair type, letting sweat marinate for days is a hard no.

But what happens when you’re caught in that frantic post-workout scramble with exactly zero minutes for a full wash before a lunch meeting, or you need to bolt back to the office? “Start by ditching the tight hair tie immediately so your scalp can actually breathe and cool down,” says Dr Keshav. Next, gently dab the moisture from your hairline with a clean microfibre towel or cotton cloth— absolutely no aggressive rubbing unless you want instant frizz from the friction. “If you have a dry shampoo formulated for the scalp, mist it strictly at the roots to absorb excess oil, or use a soothing antimicrobial spray if you’re prone to hairline breakouts or folliculitis,” she adds.

Ditch the dryer 

And then there’s the classic post-workout predicament: Reaching for the dryer while your roots are still damp with sweat. Dr Sethi advises against this, explaining that it essentially “flash-bakes” abrasive salt crystals right into your hair.

Because sweat is salty, blasting it with high heat dries it out instantly, leaving behind sharp salt crystals that grind against your hair like sandpaper. Worse, if moisture gets trapped inside the swollen hair shaft and heats up too fast, it can actually boil—creating tiny pockets of steam called “bubble hair,” which can make your strands snap off at the slightest touch.

When you look at the sheer physics of it, saving your hair from a workout requires a completely different cheat code. The secret to navigating a new fitness routine without sacrificing your strands comes down to a fundamental rule that my Pilates teacher drops during almost every class: “If your foundation isn’t stable, the rest of your form completely collapses.” As it happens, that rule applies just as much to your scalp as it does to your core.
