If you have ever had the experience of washing your hair, but still not feeling like it's fully clean, scalp buildup was likely the culprit. Once formed, scalp buildup won't always wash away with your normal shampoo—especially if you are using one without sulfates.
Scalp buildup occurs when an oily secretion called sebum accumulates alongside sweat, hair products, and dead skin cells on the scalp. It can have symptoms similar to those of seborrheic dermatitis, scalp psoriasis, and eczema. For example, each of these conditions can cause flakes to appear in the hair and scalp.
This is because sebum from the scalp can more easily cover the whole strand of hair if it is straight or thin. If people are using oily or waxy hair products or not cleansing their hair thoroughly, it can cause a buildup of oil, skin cells, and sweat in the hair. This may make it still appear greasy after washing.
An unhealthy scalp is characterized by dryness, flaking, itching or excessive build up. The hair may break easily, fall out or the texture of the hair may change.
It can be normal to see your scalp through your hair, particularly if you have naturally fine or light-colored hair. Hair density, color, and thickness all play a role in how visible the scalp is.
Have you ever scratched your scalp and noticed white, waxy buildup under your nails? That's sebum mixed with dead skin cells. It's hard for shampoo alone to wash away your oily scalp issues. And issues like stress and weather can increase the scalp's sebum production, making you even oilier.
Seborrheic dermatitis is a common, noncontagious, easy-to-manage skin condition. This type of dermatitis causes itchy red patches and greasy scales on your skin along with white or yellow crusty or powdery flakes on your scalp. “Seborrheic” refers to the “sebaceous” glands while “derm” means “skin.”
Not Getting Enough B Vitamins
What you eat does affect every inch of your body, right down to the ends of your hair. According to HealWithFood, a person's B vitamin intake directly affects a person's level of sebum (oil) production.
A healthy scalp should not have any redness or dryness and should be free of flakes or any signs of infection. Your scalp should look clean, smooth, and moisturized with no dryness on the surface.

The hair follicle can be negatively influenced by everything from sun exposure, to diet, stress, pollution, and the products we use. Poor scalp health can lead to visible signs of flaking, irritation, oily and or weaken damaged hair follicles which leads to breakage, thinning and eventually hair loss.
What is Scalp Buildup? Scalp buildup is the accumulation of “dirt” on hair and scalp from multiple origins, including sebum (oil) production, skin cells, hair products, airborne pollution, pollen, and even tobacco smoke. 5 This buildup can impact the appearance and health of the scalp and hair.
Scratching can disrupt the oil layer and add fungus to the scalp. Both of these are factors in dandruff and can trigger flaking.

Hair casts or pseudonits are 2-7 mm long, discrete, firm, shiny, white, freely movable tubular accretions that encircle the hair shafts of the scalp. [1] Even though they are not unusual, there is scarce literature on them and underdiagnosis is common.
What can cause sores or scabs on the scalp? Sores or scabs on the scalp are often harmless and clear up on their own. However, they can sometimes be a sign of a condition that may require treatment, such as psoriasis, contact dermatitis, or head lice.
Dandruff shows up as small pieces of dry skin flaking off your scalp, and it may be itchy. Dandruff is a very common condition that often comes and goes.
