well it depends what kind of hair you have and if you want it to thicken or thin your hair and if youve got hair loss, bit this is what ive found :
-Break 2 eggs (or as many as you see fit) and separate yolks from egg whites.
-Pour the egg yolks into a jar or bottle
-Pour 2 teaspoons of gin into the jar/bottle
-Close jar's/bottle's lid tightly and shake for around 15 seconds to mix the ingredients well
-Pour the tonic into the palm of your hand and massage it into your scalp,preferably in a circular motion
- -Wet the remainder of hair with the tonic and work it into your hair,allow it to soak in your hair hair for 5-10 minutes
-Rinse your hair with water and follow up with shampoo and conditioner.
hope it helped! :)
