How do I apply this serum and how often should I use it?

Dispense a few drops directly onto the scalp in sections — use the dropper or your fingertips to target areas where you notice more shedding or dryness. Massage gently for 30–60 seconds to stimulate circulation and help the oils penetrate; this also distributes the product evenly. After massaging, run any residue down the mid-lengths and ends to coat the hair shaft and reduce friction during brushing. The serum is leave-in, so do not rinse it out.

Frequency: most people start with 2–3 applications per week (e.g., every other wash day). If your scalp tolerates it well and you like the feel, you can increase to every other day. Because the formula contains essential oils (rosemary, cedarwood), daily use on a sensitive scalp may cause irritation — scale back if you notice redness or itching. On non-wash days you can still apply to a dry scalp; on wash days, apply after towel-drying for better absorption. A 100 ml bottle typically lasts 2–3 months with regular 2–3× weekly use.

Tip: combine the massage with a wide-tooth comb afterward to spread the oils through the lengths without pulling on wet, fragile strands.
