Everything people ask, and how to ask the rest.

A comb with a sealed reservoir in the body and seven fine metal tips. You fill it with oil, draw it along a part, and each tip lays one thin line of oil on the scalp. Nothing reaches the hands, the lengths, or the towel.

About 4 ml. That is a full scalp for most people, and a little more than most people need. Start with half.

Not when capped. The reservoir is sealed and the tips only release on contact with skin. Cap it after filling and carry it anywhere.

Hold the teeth under warm running water for a few seconds after each use. No soaking, no brushes. If you switch oils, rinse a little longer.

The tips touch the scalp at the part, not the lengths of your hair, so it is built to work across lengths and textures. Make a part, glide, repeat.

Anything that pours: rosemary, castor, jojoba, amla, argan, scalp serums, or your own blend. Nib has no opinion about what goes in the reservoir.

Yes. They move more slowly through the tips, so move a little slower along the part. Warming the oil in your hands first helps.

Yes. Rinse the tips, cap it, and the reservoir keeps the rest sealed until the next evening.

No. We sell the tool, not the transformation. You already have an oil you trust; this just puts it where you aimed.

Most people oil one to three times a week, often the evening before a wash. Your scalp will tell you: tight and dry means more often, greasy means less.
