Wild Sweet William
Also known as Soapwort it is still used today in textile preservation as it has been for centuries. I can say from personal experience, it is a very strong degreaser. It couldn’t be more simple to prepare and thanks to its strength I would recommend starting with a very weak solution. If you would like me to coach you with foraging, preparation or application, get in touch.
Nettle has the ability to give hair shine and is as simple to prepare as Wild Sweet William. It is much more abundant than Wild Sweet William however, it is obviously much more dangerous to forage!
There are many other plants that have for centuries been used to clean and treat hair, henna is perhaps the most commonly known one. Please leave a comment if you have anything you’d like to ask or let me know about.
