That might be fine for a dry comb, but not if it's frostbitten.You rub it on the affected areas 2 times a day until the outer layer flakes off on its own. I've never had to do that though. Usually after I apply it the next day the comb is back to normal. And I didn't add in the plantain or calendula cause I didn't have any. I'm sure if you could get some though that'd be good.
1/2 Cup Coconut Oil
2 Tablespoons Calendula petals dried
2 Tablespoons Plantain leaves
1/2 oz. Beeswax
Lavender oil
Put the coconut oil in a double boiler and turn on medium. Add plantain leaves and calendula and stir until submerged. Heat the oil until it's warm, not boiling, then turn it down as low as possible and let it stay for about 20 minutes. After time is up put the beeswax in then start straining. Once strained, add about 5 drops of lavender and mix. Pour into a jar and allow to cool before using.
