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.
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.
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.
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.
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.
Smooth Tongue
Tiny bumps on your tongue called papillae start to waste away. That makes it look and feel kind of smooth and glossy. Infections, medication, and other conditions can cause it, too. But if not enough B12 or other nutrients is to blame, your tongue also may be sore.
Vitamin D deficiency and insufficiency can cause or worsen neck and back pain and muscle spasm.
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.
Causes of greasy hair after washing
Seborrhea occurs when the sebaceous glands create excess oil, or sebum, making the skin and scalp oily. Most people with seborrhea do not have any underlying health problems. However, some people may have an underlying condition, such as a hormone imbalance.
Although the primary cause of premature hair graying (PHG) is considered to be genetic, certain environmental factors also play a role. Trace element deficiencies such as Vitamin B12, Vitamin D3, and calcium may also be associated with PHG.
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.
The deficiency of vitamin B12 can cause specific skin manifestations, such as hyperpigmentation, vitiligo, angular stomatitis, and hair and nail changes [1].
Pernicious anemia causes the tongue's surface to look smooth and appear red instead of the pinkish color of a normal tongue. The tongue might also appear thick or beefy in texture. Some tongues might even be swollen or seem to have cracks.
Vitamin B12 deficiency anaemia is usually treated with injections of vitamin B12, called hydroxocobalamin. At first, you'll have these injections every other day for 2 weeks or until your symptoms have started improving.
A diet to reduce excessive sebum production
By avoiding foods that are too fatty and too sweet, you will act to rebalance sebum production. We also advise you to include foods rich in vitamin B5 (legumes) but also in vitamin B-6 which are known to fight against oily hair.
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.
