A little white bulb at the end of a hair fallen is not in itself a cause for concern. Indicates only that the follicle has gone through various phases of the growth cycle before the thread was paid. Although this is a normal process (even in the absence of any type of hair loss disorder), the white bulb is not usually seen until, or unless the scatter becomes excessive-pushing one to examine their fallen strands.
If you suspect a problem, an examination of the bulb can provide professionals with clues as to the nature and the cause of the disorder. The shape, size and color will determine which stage of the growth cycle of hair was before the fall. and if any abnormalities are present.
The first phase of the cycle, the period of active growth, anagen is called. During this time the hair is securely anchored deeply within the follicle. Removing an anagen hair from a healthy scalp would require a pinch, forced. The tip would reveal a small rounded or slightly pigmented, light bulb that can be surrounded by a fence of sac-as reported.
After every single hair has reached its full growth potential, the follicle moves into what is known as “catagen”. Although catagen lasts only a week or two, many changes occur during this period preparing for the formation of the white bulb. The lower follicle shrinks. Disappears the inner sheath of the root. Pigmentation ceases. Cellular material (such as that of the outer root sheath) which is no longer required to support growth, began to migrate to the base of the filament.
Once all the catagen changes have occurred the follicle enters what is known as “telogen”. In early telogen remaining cells that are no longer needed to migrate to the base of the hair. Because it has ceased to pigmentation, these cells are unpigmented. These non-pigmented cells cluster together to form the “mysterious white bulb that acts as an anchor to hold the hair in the follicle while it” supports “for about three months before being released. The telogen phase is also referred to as the rest.
Any hair that fall with an attached white bulb indicates that it has cycled through the telogen phase before falling. Due to the shape, these filaments are also referred to as animal hair club. This feature will be present in daily normal shedding. Unless the shedding is excessive, there is no cause for concern.
The most common condition that causes excessive shedding with a white bulb is associated with telogen effluvium. Because each hair follicle at any stage of the growth cycle may be affected, fallen strands can be of different lengths.
With alopecia areata hair are often spread during the telogen phase, but in some cases that can be paid during the anagen or it can break. The threads interested may have an “exclamation point.” A small portion of the right wire to the scalp becomes very thin, giving the appearance of an exclamation mark. Because the hair is very thin at this point can also break. Although the most common form of alopecia areata causes bald patches, there are other variations of this condition that cause other severe patterns of baldness.
The absence of a visible white light bulb might indicate that the hair fell during the anagen phase, as in the loose anagen syndrome or anagen effluvium. It could also indicate that broke off, rather than fell out.
