The white "pebble" in your hair could be one of several common things, ranging from simple product buildup to a mild infection. The most likely causes are sebum plugs, hair product residue, or a condition called white piedra.
White piedra is a superficial fungal infection of hair caused by Trichosporon species. It presents clinically as white nodules encasing the hair shafts and may lead to increased fragility. It can usually be differentiated easily from clinically similar conditions based on clinical and microbiologic features.
Myth: A hair falling out with a white bulb attached means it won't grow back. False! The small white lump at the root is simply part of the hair follicle lining, similar to skin. It doesn't mean the follicle is dead and hair can continue to grow normally.
Sebum plugs are small, waxy deposits that can form on the scalp when the natural oils produced by your scalp mix with dead skin cells, dirt, and other impurities. They are referred to as "scalp acne" or "follicular keratosis."
With a regular haircare routine, you can clear all the crystallized sebum balls on your scalp and maintain healthy sebum levels.
You've probably heard that squeezing or picking at a pimple is not a great idea, and the same goes for sebum plugs. By squeezing, you can push the contents deeper into the skin or break the pimple open, which allows the bacteria inside the pimple to spread and any bacteria on your hands to enter the pore.
From a distance, sebum plugs often appear as little black dots, but they are actually a clearish-yellow color (like sebum itself). If sebum plugs then mix with dead skin cells and bacteria, the combination can trigger acne, typically in the form of whiteheads or blackheads.
How To Treat Sebum Plugs
In most cases, antifungal shampoos are employed, with 2 % ketoconazole shampoo being considered the most effective.
Adult lice may be about the size of a sesame seed or slightly larger. Lice eggs on hair shafts. Lice eggs, called nits, stick to hair shafts. Nits may be hard to see because they're tiny.

The loss is diffuse and involves the entire scalp rather than discrete areas. The hair appears uniformly sparse. Regrowth is usual with successful treatment of the thyroid disorder, though it will take several months and may be incomplete.
Key takeaways: Key nutrients for healthy hair, skin, and nails include biotin, vitamin C, omega-3 fatty acids, and collagen. Most people can get these nutrients from their diet. But supplements may help if you have a deficiency, a restricted diet, or persistent hair or skin issues.
Sometimes when we touch our scalp with fingertips, especially in case of oily skin and if we are particularly careful, we might feel some very small sand grains. These are nothing but sebum leftovers, dandruff or “pollution” which lie on the scalp and prevent it from breathing properly.
Dandruff causes white or grey flakes of skin to appear on the scalp and in the hair. The flakes are often more noticeable in darker hair and if they fall from your scalp onto your shoulders. Your scalp may also feel dry and itchy.
Piedra is the Spanish word for 'stone' and that is reflected in the appearance of this ailment. You'll find white, grey, or tan, pearly nodules surrounding your hair shaft. These are soft and loosely clump together on your hair. You'll find white Piedra on scalp hair, facial hair, and body hair.
What is the differential diagnosis for piedra?
Itchy and Flaky Scalp
An intensely itchy scalp is often the first sign of a fungal infection. The constant urge to scratch can be overwhelming as fungi colonise the skin. White, flaky scales typically develop and may shed from the scalp, resembling severe dandruff.
These agents may be effective in treating white piedra.
Sebaceous hyperplasia appears as small, shiny, spongy bumps on the surface of the skin. Usually they appear on the face, but they could develop anywhere on the body. The bumps may be a similar color to the surrounding skin, or slightly pink or yellow. They may also have a small indentation in the middle.
Washing your scalp with warm water is the first step in removing sebum clogs from your head. After that, use a gentle shampoo and massage your scalp with your fingertips. This aids in the removal of all hardened and dried sebum from the scalp. Sebum build-up occurs on the scalp rather than on the hair strands.
Vitamin B5 (pantothenic acid): A deficiency in this B-vitamin can lead to excess sebum production and acne breakouts.
That white residue is usually a combination of excess oils, dead skin cells, and leftover product buildup. It's a sign your scalp needs a proper cleanse rather than scratching.
