Red henna, or Lawsonia inermis, is a green powder that dyes light hair to a deep orange. Using henna to color your hair requires mixing the powder with water to a mud-like consistency and working the thick paste through your locks. It is a dye that takes a number of shampoos to fade. If you have dyed your hair with henna and do not like the way it looks, you can strip some of the color out of your hair with mineral oil.
Saturate your hair with rubbing alcohol using cotton balls. Keep the alcohol off your scalp. Allow the alcohol to stay in your hair for five to 10 minutes.
Coat your hair with mineral oil. Do not wash out the alcohol; just apply the oil over it.
Cover your hair with a plastic shower cap. Apply heat using a blow dryer or hood dryer for 30 minutes.
Remove the shower cap and rub clarifying shampoo through your hair without water.
Get into the shower and wash the shampoo and oil from your hair with hot water. Repeat as necessary until you have washed all the oil out of your hair.
Follow the shampoo with a deep-conditioning treatment to restore moisture to the hair.
