Pour the 1/3 cup of water into a small pan and bring to a simmer.
Remove from the heat and add the horsetail.
Cover, and let infuse for 5-10 minutes.
Strain and set aside.
In a shallow bowl, pour the ¼ cup of room temperature water.
Sprinkle the gelatin over the top and allow it to gel for a few minutes.
Whisk in the hot horsetail infusion.
In a small bowl, thoroughly combine the honey and essential oils.
Stir the gelatin mixture into the honey. Keep stirring until you no longer see tiny bubbles, as this means it's mixed. The honey helps to safely disperse the essential oils into the hair mask. If not using any essential oils, then just add the honey straight to the gelatin mixture.
Whisk the egg in. Make sure that the gelatin mixture isn’t too hot when adding the egg, or you’ll end up with scrambled egg in your hair mask!
Apply the prepared hair mask liberally to the hair until all strands are thoroughly coated.
Allow the mixture to sit on the hair for 5-10 minutes, but don’t let it dry. A shower cap can be used to keep the hair moist if you want it on the hair for longer.
Thoroughly rinse out. Follow up with an apple cider vinegar rinse if needed to remove all of the hair mask.
If the hair is a little stiff afterwards, then apply a little coconut oil to your palms, and massage over the hair. Or use a conditioner and rinse as usual.This mask can be used up to once a week, or less frequently if hair becomes stiff with once a week use.
