In a small bowl, add sugar, oil of choice, apple cider vinegar, and essential oil.
Mix together well.
Store in a glass container.
To Use:
Wet hair and take out 1-2 tbs of the scalp scrub.
Apply a small amount of the scrub in a circular motion on your scalp massaging with your fingertips. Focusing on more troubled areas.
Allow the mixture to sit on your hair for a few minutes while you do wash up, shave, etc.
Rinse with warm water until all the sugar is out.
Apply regular shampoo and wash hair. Follow up with conditioner on the ends of your hair. Rinse and dry hair.
Notes
I like to use this in the shower. It is quite messy and this helps contain the mess.
You can apply this with dry or damp hair. Personally, I like using it on damp hair.
I like to use apple cider vinegar in this recipe because it is something I always have on hand, but you could also substitute with lemon juice.
If you have color-treated hair use apple cider vinegar over lemon juice since lemon juice can affect the color.
While it is optional to use essential oils, some may have some benefit to hair health. Especially rosemary (can help promote hair growth) and tea tree (anti-fungal properties).
You may need to wash your hair twice to get out all the oil. It depends on the type of shampoo you use.
