How to Avoid Oily / Greasy Hairs

Wash Your Hairs Regularly   

Wash your hair frequently. Many experts of hair and scalps believe washing hairs once or twice daily is a good approach to keep your hair healthy as well as oil-free.


Keep Water Temperature Low

Dermatologists always advise to keep the shower short and temperature low.
Warm water rinses all-natural productive oils from your hairs and scalp, triggering sebaceous glands to produce more oil.
So, whenever you wash your hair with warm water remember at the end, rinse with cold water which helps in closing all the pores on your scalp.

Use Dry Shampoo

Dry shampoo absorbs your hair’s excessive oil, leaving it to look clean and refreshed.
It will not suck up oil from your scalp though, but it will extend the intervals between your hair wash.

Avoid Using Conditioners in Scalp

Apply Conditioners from mid shafts to end avoiding scalps. Conditioners are for hairs, using it on the scalp causes oily hairs. But Shampoos can be used in scalps.

Eat Vitamin-B Rich Food

Vitamin-B direct link to level Sebum production. Vitamin-B such as biotin affects panthenol and sebum levels, which help hairs stay healthy, shiny and helps reducing oily hairs.

Limit Using Heat Hair Stylers

So, whenever you use your dryer, straightener, etc use them in the lowest temperature settings.
