Avoid intense heat for a while
Right after care, your scalp is more sensitive than usual. Avoid saunas and hot blow-drying on the day of your treatment.
Postpone perms and coloring
For 1–2 days after care, it's best to avoid treatments that strongly irritate the scalp, such as perms or hair coloring.
Keep up home care suited to your scalp type
To maintain the effects of your care longer, continue a consistent home-care routine at home that matches your scalp type.
Be careful with exfoliating products
If you received a scaling treatment, avoid additional exfoliating products such as scrubs for at least 2 weeks.
How does the Medical Head Spa proceed?
We first assess your scalp condition through consultation and precise analysis, then compose a 1:1 customized deep cleansing and device care based on the results. Finally, we show you a before/after comparison and guide you through home care you can keep up consistently.
How often should I get it?
The recommended frequency is 1–2 times a month, though it can vary depending on your scalp condition and concerns. If your scalp is oily or troubled, come a little more often; if it's healthy, you can space visits out.
Do I really need a head spa?
Daily shampooing only cleanses the surface of the scalp. No matter how thoroughly you wash, it can't reach the sebum and dead skin cells inside the pores. Just as you get dental scaling even though you brush every day, your scalp also needs regular care of impurities and dead skin cells to stay healthy.
How is it different from a regular head spa?
A regular head spa judges your scalp condition by a therapist's touch and eyes. Derna uses clinical scalp diagnostic equipment to take two-stage macro and micro measurements, then reviews the resulting report with you to set today's care direction. Deciding by measured data rather than intuition is the biggest difference.

Derna's Medical Head Spa is a scientific scalp solution that goes beyond a simple scalp massage. After accurately assessing your scalp condition through precise analysis, we select only the care your scalp needs right now — from clearing built-up dead skin cells and impurities to boosting the absorption of active ingredients and stimulating scalp circulation — and complete it with professional products and devices.
