The white bulb at the end of your hair is essentially a bundle of protein, known as keratin. The role of the white bulb is to help the hair follicle root to the scalp, which then allows the hair to grow until it is shed.
A white bulb at the end generally indicates that the hair is in the resting phase, and they a new hair has pushed it out (causing it to shed). This is the natural process of hair growth. A new one is simply taking its place.
Shedding hair with a black bulb at the end typically indicates that the hair has completed its growth cycle and is in the telogen phase, ready to fall out naturally. This shedding is a normal part of the hair growth process, and new hair will grow back in its place.
If you accidentally pull out a strand of your hair and it has a ball (bulb) on the end of it, you didn't pull out the follicle, and instead, you removed your hair root. That root grows back and your hair will grow back, too.
It's your hair follicles. Sometimes when you shed a hair from the root there will be a little white bulb at the end of the hair. This happens when the hair is ready to fall out as opposed to breaking. Sometimes the bulb will separate from the hair and stay loosely in the scalp. When scratched it will come loose.
The white bulb at the end of your hair is essentially a bundle of protein, known as keratin. The role of the white bulb is to help the hair follicle root to the scalp, which then allows the hair to grow until it is shed.
And remember, if you ever find yourself asking, “Can you squeeze an ingrown hair out?” the answer is a careful no—stick to safer, smarter solutions for your skin's sake.
Many of us, especially in cold and dry weather, may see white flakes falling from our hair and assume they are dandruff. Flakes from dry scalp are far more common than true dandruff. Dandruff is caused by overgrowth of a yeast (malassezia) present on most normal skin. Less washed hair can result in a more oily scalp.
A visible scalp through your hair can be a sign that it's thinning (but not always). The factors that contribute to thinning hair (and thus a visible scalp) include stress, diet, vitamin deficiency and ageing.
The black dots are due to remnant of the upper part of the hair root, which remains adherent to the hair-follicle ostium. Hair powder, also known as hair dust, on the other hand, is caused by complete destruction of the hair shaft, leaving a 'sprinkled hair residue' [1].
A healthy bulb is round and its diameter is decidedly wider than that of the hair shaft. Each hair is surrounded by many nerve endings. The hair shaft has a diameter of around 70-100 μm and is composed of three continuous layers called, from the inside out, the medulla, cortex and cuticle.
If you notice a tiny bulb at the end of one of your hair strands, you're probably looking at a club hair. Don't stress — club hairs aren't an issue in themselves. Club hairs look like regular hairs, but they have a little light-colored or black bulb at the end of the hair strand. Club hairs are normal.
White piedra is a superficial fungal infection of the hair shaft. It can affect people of any age and tends to occur in semitropical regions of the world. Shaving the affected area and completing a short course of a topical antifungal can treat white piedra.
Effective treatments for some types of hair loss are available. You might be able to reverse hair loss, or at least slow it. With some conditions, such as patchy hair loss (alopecia areata), hair may regrow without treatment within a year. Treatments for hair loss include medications and surgery.
"The white bulb at the end of the hair is keratin (or protein) and is the same keratin that makes up your skin and nails. A white bulb is not indicative of hair loss," said stylist Carrie Capalbo of Salon YOSHIKO. "It's part of the lining of the hair follicles.
The white bulb indicates that the hair was in the resting (telogen) phase of the hair growth cycle. Normally, about 10-15% of your hair is in this phase, but with telogen effluvium, up to around 70% of your anagen hair (hair that is actively growing) may enter the resting phase and fall out prematurely.
Catagen phase
A bulb of keratin attaches to the bottom tip of the hair and keeps it in place while a new hair begins to grow below it. A hair pulled out in this phase will have the bulb of keratin attached to it which appears as a small white ball on the end of the hair.
Plucking your pubic hair can be painful and takes a long time. Plucking can cause redness, swelling, itching, irritation, and damage to the skin. It can also result in ingrown hairs (where the hair curls backward or sideways under the skin) and infection.
What Causes Itching During Hair Regrowth? Itching during hair regrowth primarily stems from the way hair re-enters the skin. As the new hair grows, it can curl back into the skin, leading to irritation and itching. This is especially common if you have coarse or curly hair.
Myth: A hair falling out with a white bulb attached means it won't grow back. False! If you notice that some of your fallen hairs have a small white lump or bulb at the root, you shouldn't worry. This does not mean that the root of your hair has been removed, or that the follicle is dead.
Don't tweeze ingrown hairs. Before shaving wash the affected area using a warm washcloth or soft-bristled toothbrush. Use a circular motion for a few minutes. Apply a warm, damp cloth for a few more minutes.
Typically, dead hair follicles lead to a smooth patch of bald skin on the scalp – it typically will not look like general hair thinning. Doctors and hair specialists can get a look at your hair follicles by using a microscope.
