Will this weigh down fine hair or make an oily scalp worse?

The oil phase — castor, olive, wheat germ, walnut, and cedar seed oils — is intentionally rich to form a protective layer on the scalp and reduce moisture loss. That richness is exactly what helps dry, tight, or flaky scalps, but it means the product has a substantial texture.

If you have fine hair or a scalp that gets greasy quickly, adjust three variables: amount, area, and time. Use half the quantity you would for thick hair. Concentrate application only on the scalp and the first 2–3 cm of roots — avoid the mid-lengths and ends entirely. Reduce the leave-on time to 15–20 minutes. Shampoo twice as described, and finish with a lightweight conditioner only on the ends.

Test once a week for two weeks. If roots look flat or the scalp feels coated the next day, cut frequency to every 10–14 days. The burdock and black radish extracts are included for their traditional use on tired-looking roots, not to regulate sebum production, so they won't "fix" oiliness — but the right technique keeps the treatment from adding to it.
