Potato water is used to treat dandruff related to seborrheic dermatitis or an imbalance of the sebaceous glands.
It is a natural astringent, deeply cleanses the scalp and, due to its high starch content, absorbs oil.
It has vitamin A, C and zinc, which is why it helps prevent hair loss. Dandruff has nothing to do with poor hygiene or dirt. We must get that idea out of our mind.
The overactivity of the glands can be caused by multiple reasons such as sudden changes in temperature and humidity, use of poor quality products or irritating substances for the hair.
Using potato water as a tonic is very beneficial for this problem. The change is drastic and immediate.
You need to wash a medium potato, peel it and chop it and incorporate it into the blender with a glass of water.
The mixture obtained can be passed through a strainer and the resulting water is the wonderful hair tonic. Store in the fridge and it's ready to use. (This mixture can only be used for 2 weeks).
Application: you should place the potato water at the root of the hair every other night. It is recommended to complete the treatment for a month and then repeat every 15 days to deeply cleanse the scalp.
