In a small pot, bring water to a boil.

Reduce to a simmer and add the slippery elm bark.

Simmer for 15 minutes. Liquid will reduce by about half.

Allow to cool and then strain. I recommend using cloth (like a bit of muslin or cheesecloth) to strain because it is hard to press the mucilage through a mesh strainer as I discovered.

Once strained, transfer your liquid to a spray bottle.

Add in the drops of essential oil, place the cap on, and give a good shake. Your hair detangler is now ready to go!

Spray onto wet hair and comb through.
