We recommend washing your hair either the night before or the morning of your exosome treatment session to ensure your scalp is clean and free from oils, dirt or product buildup. A clean scalp improves the absorption of exosomes and minimizes the risk of irritation. Avoid heavy oils, gel, mousse or hair spray, as these can obstruct access to the scalp.
After the session, you may be advised to avoid washing your hair for 12–48 hours (depending on treatment type) to allow the exosomes to fully integrate and begin their regenerative activity. Washing too soon may reduce the therapy’s effectiveness and irritate the treated areas, especially if injections were used.
Keeping the scalp clean and free from chemicals before treatment ensures the best possible environment for exosome penetration and follicle stimulation. Your clinician will confirm exact timing based on whether your session involves topical exosomes, microneedling-assisted application or direct injections.
