Ans - A deficiency in vitamin B6 and zinc can contribute to an oily scalp. These nutrients help to regulate oil production and promote a healthy scalp.
But if your hair is too oily, it could be low zinc. Zinc is one of the most important trace minerals yet 2.2 billion people are zinc deficient. Zinc helps decrease your androgens and DHT, which is a powerful form of testosterone that can cause the sebaceous glands to produce more oil.
Persistently greasy hair may be due to an overproduction of sebum, which can sometimes indicate an underlying health condition. However, the way people wash and care for their hair, and the type of hair products they use, may be the cause.
When you are getting enough B vitamins (B6 is a great one for scalp health) you are able to regulate sebum production, which combats greasy hair.
One hormone, androgen, surges, increasing the production of sebum in the scalp. Sebum is vital to our hair, protecting it from environmental damage and keeping it supple, but too much can lead to a greasy look.
Most of these hair follicles also contain the sebaceous glands, the glands that produce oil. These oil glands keep the skin and hair healthy and moisturized. They also help prevent skin infections. Sometimes, these glands can produce too much oil, causing oily skin and hair.
Excessive washing
Over-washing can make your hair look greasy because it strips the hair of its natural oils. This loss of natural oils causes the body to overcompensate by producing more sebum. Over-conditioning can also lead to greasy hair because it weighs down the hair and this in turn increases oil production.
Vitamin D deficiency
Vitamin D is responsible for regulating the sebum content in the body. A deficiency could lead to an imbalance in our scalp oil levels.
Vitamin D. Vitamin D is a fat-soluble vitamin that works alongside our sebaceous glands to regulate sebum production. Vitamin D helps our bodies protect against insulin resistance which can lead to oily skin as insulin stimulates the overproduction of sebum.
You may be experiencing seborrhea, a common skin condition that causes your glands to produce too much oil [1]. Or you may be undergoing hormonal changes which disrupt the oil production balance in your skin and hair.
Vitamin B contributes to the production and regulation of sebum levels. A deficiency in this can cause your body to react by producing more oil. Foods that are high in Vitamin B include whole grains, eggs, meat and dairy.
Certain medical conditions, such as polycystic ovary syndrome (PCOS) and hypothyroidism, can also cause oily hair. These aren't the only medical reasons for greasy hair, so it's worth speaking with your health care provider to rule out any conditions that could be causing excess oil.
If your hair is greasy after just one day, it could be due to factors such as overactive sebaceous glands, the use of heavy hair products, hormonal fluctuations, or even your diet.
1 Consider taking a vitamin B2 (riboflavin) and vitamin B6 (pyridoxine) supplement, which can help combat greasy hair by regulating sebum production. Luckily, vitamin B is found in a lot of foods including beans, meat, poultry, fish, and some fruits and vegetables.
Hormonal Imbalances
Androgens are hormones that play a role in regulating the activity of sebaceous glands. An increase in androgen levels can lead to an overproduction of sebum, resulting in oily hair.
Overproduction of Sebum
Sebum is the natural oil produced by your scalp's sebaceous glands. It plays an important role in keeping your scalp and hair moisturized and protected. However, when your scalp produces too much sebum, it can make your hair look and feel greasy quickly, even when it's freshly washed.
Low estrogen skin tends to be thinner, showing more visible blemishes and wrinkles. Low estrogen skin also has lower collagen reserves. Collagen is the naturally occurring protein that keeps your skin looking smooth and full.
