“A black dot is defined as a hair in which the upper part of the hair root remains adherent to the hair-follicle ostium, giving the macroscopic appearance of a macrocomedo.
Black dots correspond to remnants of hair shafts in the follicular ostia and cannot be removed mechanically. They are usually associated with other forms of broken hairs. The second trichoscopic finding is hair dye; if hair is improperly washed, dye can deposit on the scalp and may even penetrate the follicular ostia.
Club hairs are an end product of final hair growth and feature a bulb of keratin (protein) at the root tip of a strand. This bulb keeps the hair in the follicle until it sheds and the hair growth cycle starts over.
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.
Black dots, also called comedo-like cadaver hairs, can be found in almost 50% of alopecia areata patients and indicate disease activity. Trichostasis spinulosa is a follicular disorder resulting from the retention of numerous hairs surrounded by a keratinous sheath in dilated follicles.

These could represent hairs that are just starting to grow and are pushing thru the surface of the scalp. they could also represent a broken or damaged hair although more commonly the hairs break mid shaft somewhere not at the very base.
Pulling out hair by your root may damage your follicle temporarily, but a new bulb will eventually form, and new hair will grow again through that follicle. According to the TLC Foundation for Body-Focused Repetitive Behaviors, it may take a few months or more than a year in some cases.
Dead hair follicles are most evident when the scalp's skin (where the hair once grew) becomes smoother and shinier in appearance. In other words, there'll quite literally be no hair there/no signs of regrowth if your hair follicles are completely dead.
As long as it is not happening excessively or you are not noticing it on every hair strand that falls out, losing hair with a bulb at the end of it is perfectly normal. It just means that you lost the hair in the third phase of the hair growth cycle rather than during the fourth phase.
When done correctly, plucking can stop hair growth for up to six weeks, longer than many alternative hair removal methods. The reason plucking stops hair growth for so long is because it removes the hair directly from the hair follicle, the part of the hair strand that is anchored to your skin.
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].
The hair's bulb and root aquire a soft, gelatinous keratin.
The inner root sheath (IRS) is an important structure of the lower part of the hair follicle that surrounds and protects the growing hair.
Blocked hair follicles range in severity from mild to severe. They start out looking like small and irritated red pimples. Over time, they may look like pus-filled lumps, cysts, or boils. They may abscess and drain pus and blood.
Ingrown hairs can look like raised, red, itchy spots on the skin. Sometimes you can see a hair trapped under the skin. You may be more likely to get ingrown hairs if you have coarse or curly hair. Infected ingrown hairs can be painful.
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.
Actually , it's absolutely normal . There is nothing to worry about . It can happen because of pollution , excessive heat or because of the bad hair routine which many people follow because of which they have to suffer through greying of hair .
It's important to remember that hair follicle cells die, but hair regrows after the follicles rest. When your hair follicles are dead, they do not regrow hair. You can inspect your scalp and look for signs of hair growth.
For the most part, hair damage is permanent because hair is actually a collection of dead cells, making them beyond repair. The only real cure is time, a pair of shears, and taking steps to prevent new damage.
Simple baking soda may help open roots. Add two teaspoons (10 mL) of baking soda to a cup (240 mL) of lukewarm water and then stir until the baking soda dissolves. Pour the mixture over your head and work it into your scalp using your fingertips. Let it sit for a couple of minutes before rinsing.
Results: The mean length of a scalp hair follicle is 4.16 mm. The infundibulum measures 0.76 mm, the isthmus 0.89 mm, and the inferior portion 2.5 mm. The insertion of the arrector pili muscle is located 1.65 mm deep. CK15 immunoreactivity starts at a depth of 1 mm and extends down to 1.8 mm.
“When done correctly, plucking removes the entire hair from the follicle, keeping it from growing back for up to 6 weeks. If you tweeze with skill in an area such as the eyebrows, it can give you more control than waxing,” Gonzalez says. Here are some tips to tweeze safely.
"These dots indicate that the hair is fractured or broken,' says celebrity hairstylist Nick Stenson, artistic director of Matrix.
This pressed oil from the seeds of the Nigella sativa plant—a flowering shrub species native to Western Asia, Northern Africa, and parts of Europe—has long been thought to help with hair growth, giving limp or thinning locks a boost, like other popular oils are said to do.
