Onion Peel Water as a Final Rinse
Dry onion skins boiled, cooled and strained as a mild last rinse. Smells strongly and may tint very light hair; no promise of regrowth.

A mild rinse from kitchen waste
Dry onion skins boiled in water give an amber liquid, and it is a viral hair rinse because it costs nothing. It is a mild last rinse that may add a little shine. It is not a growth treatment, and claims about regrowth have no firm proof. It may tint very light or coloured hair.
Boil a handful of clean, dry skins for ten minutes, cool and strain well. Make it fresh and use the same day. Patch test first and keep it out of the eyes. Skip it on a sore, broken or itchy scalp.
