This is a leave-in cosmetic serum, not a drug. It can usually sit in the same routine as minoxidil or other topical treatments. A practical order: wash and towel-dry hair, apply the DR.SANTE serum to the scalp, massage and let it absorb for 5–10 minutes, then apply any prescribed medication per your doctor's instructions. This avoids dilution or interference.
If you use multiple cosmetic serums (e.g., one for hydration, one for density), alternate days or use one in the morning and the other in the evening rather than layering several at once — too many leave-in products can create buildup on the scalp. The dye-free, lightweight texture of this serum makes it compatible with most routines.
If you are under dermatological care for hair loss, scalp inflammation, or a diagnosed condition, mention this product to your specialist before adding it. Sudden or pronounced thinning with scalp discomfort warrants professional evaluation — a cosmetic serum is not a substitute for medical assessment.
