After a workout, let the scalp cool, remove trapped moisture and decide whether it needs a full cleanse based on sweat, buildup, odor and comfort. Do not cover a damp scalp for hours or use heavy oil to mask persistent itching or flakes.
Right after exercise
• Remove tight hats, scarves or bands.
• Blot sweat gently with a clean towel.
• Release the hair from a tight style.
• Let the scalp and roots dry before covering them.
When to cleanse
There is no universal rule that every workout requires shampoo. Cleanse when the scalp feels dirty, oily, itchy, coated or has persistent odor. Apply shampoo primarily to the scalp, rinse thoroughly and condition the lengths.
The American Academy of Dermatology notes that wash frequency should reflect how quickly hair and scalp become dirty or oily. Curly and textured hair may need less frequent shampooing than straight, oily hair, but buildup and flakes should not simply be ignored.
Refresh the style without coating the scalp
If the scalp feels comfortable and the lengths only need reshaping, dampen selected sections and use a small amount of leave-in on the hair—not automatically on the scalp. Refreshing should not replace cleansing when residue has accumulated.

When symptoms deserve attention
Sweat can make an existing scalp problem more noticeable, but recurring flakes, burning, sores, marked tenderness or significant shedding can have several causes. Do not try to diagnose them from appearance alone. Seek a board-certified dermatologist when symptoms are persistent, severe or worsening.
