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].
Black Bulb: A black bulb at the end of a hair strand typically indicates that the hair has been pulled out or has naturally fallen out from the follicle. This is often seen in cases of telogen effluvium, a common type of hair loss where hair follicles enter the resting phase prematurely.
The white element you see at the end of your hair when you pull it is likely the hair's bulb, also known as the hair follicle. This bulb is the part of the hair that is embedded in the scalp and is responsible for hair growth.
A black dot could result from a fungal infection on the scalp known as tinea capitis or traction alopecia, causing broken hairs from tight hairstyles that look like black specks. Black dots could also be a symptom of alopecia areata, an inflammatory disease, or even a sign of scalp melanoma.
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.

For targeted dark spot repair, incorporate products with melanin-inhibitors, antioxidants, and exfoliating acids into your daily regimen.
So what is this small white particle? In fact, the white small particles in the roots of the hair are fat particles composed of sebum and oil.
This white bulb at end of hair is called a club hair, and it essentially is a hair that includes a bit of protein on the end of it that is supposed to root the hair to the scalp. When you lose a club hair, it just means that you have lost a piece of hair that is in the telogen phase of the hair growth cycle.
Waxing and plucking can damage the hair follicles, causing new hair growth to be slower and thinner over time. These methods are not considered permanent hair growth, though.
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.
It is a common mistake that a white bulb at the end of a shed hair shaft is the root or the hair follicle, and when they see it, they have permanently lost that hair. The white bulb commonly seen with shed hair is actually keratin, or dead skin, with the hair follicle remaining in place to regrow a new hair strand.
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.
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.
Another reason for skin darkening is the friction caused by shaving or waxing. The repeated rubbing and pulling of the skin in the bikini area can cause damage to the skin's surface, leading to darkening.
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.
There's an oft-repeated myth that pulling out one gray hair causes ten more to grow in its place. That's not true—but it's still not a good idea to pluck your grays. While yanking out a stray gray or two may not seem like a big deal, over time, it can become one.
Squeezing out the hair follicles can disrupt the hair removal process and damage the hair follicles, potentially causing scarring and hyperpigmentation. Squeezing can also introduce bacteria into the skin, leading to infections and even breakouts.
In conclusion, an itchy scalp does not necessarily mean hair growth. In fact, it is more commonly linked to hair loss and scalp problems. Understanding this myth and its misconceptions is essential for proper hair care.
Pull Test and Tug Test
This simple test measures the severity of hair loss. During a pull test, a dermatologist grasps small sections of hair, about 40 strands, from different parts of the scalp and gently tugs. If six or more strands fall out, you have what's known as active hair loss.
