Structure and Composition of the Hair Follicle
Diseases of the Hair Follicle
- Thinning of hair follicles - the initial stage of the disease of the hair follicle.
- Atrophied hair follicles are follicles that produce rare and thin hair.
- Sleeping hair follicles - these follicles will never be able to produce hair.

Greasy GlandThe sebaceous gland (figure 2 see the figure) is an integral part of the hair follicle and scalp. The main function of the sebaceous gland is the secretion of a specific secretion - sebum .
Being evenly distributed over the entire length of the hair (figure 1 see the figure), the secret of the sebaceous gland gives the hair a shine and a rich color. However, sebum performs a utilitarian function to protect the surface of the scalp (scalp) from harmful substances from the outside, from microbes and infections.
The secret of the sebaceous gland is excreted in abundant areas with strong emotional stress. In this case, the sebaceous gland squeezes the follicle of the hair (see the figure), thus compressing the sialasal gland burdened on the one hand by a strained muscle, on the other hand, by the outer wall of the follicle.
At this stage, there may be problems associated with excessive sebum secretion or with its almost complete absence.
Depending on the activity of the sebaceous gland function , the type of hair depends . There are 4 main types of hair:
- Greasy hair - when hyper production of sebum predominates.
- Normal hair is the case when the sebaceous gland functions normally.
- Dry hair - when the sebaceous gland does not function fully or in insufficient quantity emits sebum to effectively "lubricate" the hair and scalp.
- Mixed type of hair - people who wear long hair are usually ranked here, when all the hair is not lubricated along the entire length with sebum, it remains fat at the roots and dry at the tips.
Excessive Sebum SecretionExcessive secretion of sebum, can occur not only in the aftereffects of stress, but also as a result of hair loss and subsequent hair thinning.
The hair on our head is not just an ornament, although most people, mostly representatives of the pre-carp sex, use them for this purpose. Like the secretive gland, evenly distributed over the surface of the scalp, the hair on the head also performs a utilitarian function. Thus, the surface of the head is protected by hair, and a thin fatty layer distributed over the surface of the scalp-the sebaceous gland secretion.
Why is there an excessive secretion of sebum in hair loss ?
An interesting moment is passing by. The fact is that with hair loss, one of our "external protections" of the scalp, disappears, literally speaking - drops out. And sebaceous gland, takes on the function of "additional protection" of the scalp - begins to secrete several times more secret to compensate for the lack of hair with a thicker fat layer.
In this case, often, there is an aesthetically unattractive effect when the hair on the head is already scarce, while they are still fatty, as it were, "sticking to the scalp." Then govrjat, that "the head quickly gets dirty" and it should be washed once a day though earlier it was necessary to wash once a week.
Treatment of such a deviation in the operation of the general gland with hair loss, includes a number of measures: to increase the volume of hair, treatment of alopecia as such pathological process, after qualitative hair treatment, regulation of sebaceous glands function.
In the rays, if the abundant sebum secretion is caused by stress, along with the recovery of the onion bulbs, therapy is used to normalize the work of the sebaceous gland.
Decreased Sebum Secretion. Dry, lifeless HairAnother deviation in the work of the sebaceous gland is a reduction in the secretion of sebum. In this case, as a rule, notice the dryness and lifelessness of the hair. They say, "hair like straw," "like a patch," constantly "sticking out in different directions."
As in the case of excessive sebum secretion, a decrease in secreted secretion may also be caused by stress or chronic stress. When the involuntary muscle is already so atrophied that it is not able to squeeze the sebaceous gland. In this case, the head massage, the treatment of low-power electric currents is shown.
Reducing the secretion of the secretion of the sebaceous gland may appear in cases of occlusion of the mouth of the hair follicle, then the secretion of the sebaceous gland is not able to fully cover the scalp. Then, they say - "fat hair at the roots and dry at the tips."
If you have a suspicion of a violation of the sebaceous gland, you know, this is a possible consequence of some pathological process.
