The correct usage is: first, wash the hair loss place so that the hair tip does not drip, apply essential oil and massage for 3-5 minutes. Apply the mask to the hair and massage for 3-5 minutes. Cover the heating cap and heat 10- 15 minutes. Hair is cold, just wash it with warm water. Hair is elastic and shiny when it is dry.
Essential oil is a volatile aromatic substance extracted from flowers, leaves, stems, roots or fruits of plants by steam distillation, extrusion, cold soaking or solvent extraction. Essential oils are divided into diluted and undiluted, such as cactus seed oil. Essential oils are highly volatile and will evaporate quickly once they come into contact with air. For this reason, essential oils must be stored in dark bottles that can be sealed.
