Types of alopecia that exist

In the face of unusual hair loss that also accompanies bald spots, it is essential to go to a hair clinic to receive a diagnosis. In this way, the medical team determines the type and degree of alopecia of the patient. But, How many types of alopecia are there? The truth is that there are several, and depending on the type in question, some hair treatments or others are chosen, and it can even influence whether or not a hair graft can be performed.

For that reason, since Hospital Capilar, hair clinic in Madrid, Murcia and Pontevedra, we tell you what are the different types of alopecia that exist, how to identify each one and its main treatments. Next!

Types of alopecia that exist

There are many factors that can cause hair loss in men and women. Depending on the pattern of hair loss, the state of the scalp and the symptoms with which it occurs, it is determined which of the main types of alopecia is treated. In this way, the medical team studies whether hair loss is reversible, the most recommended treatment, as well as the feasibility of hair grafting if necessary, among others. 

The different types of alopecia can be divided into two large groups: scarring alopecia and non-scarring alopecia. Within each one we find other types of alopecia but with a characteristic in common: the presence of scar tissue or, in the case of non-scar tissue, the absence of it.

non-scarring alopecia

Non-scarring types of alopecia are those that do not involve the appearance of scars on the scalp. These are usually the most common and easiest to treat, as well as being the most viable when performing a FUE hair graft. 

Androgenic alopecia

La androgenic alopecia It is the most widespread, especially among the male audience. It is due to genetic and hormonal factors, specifically due to the action of the so-called Dihydrotestosterone. It attacks the hair follicles causing hair miniaturization and the subsequent fall. This hair loss is not reversible, so the hair that falls out will not grow back. The only way to recover hair in these cases is with a hair implant. 

It usually begins in the area of ​​​​the entrances and the crown of the head, extending to the rest of the scalp little by little. Androgenic alopecia is measured with the Hamilton-Norwood scale in men, and in the case of female androgenic alopecia with the Ludwig scale

Diffuse alopecia

La diffuse alopecia It is that characterized by a miniaturization of the hair, which gradually loses its thickness until it disappears completely. Maintenance treatments help prevent this miniaturization from occurring, but if it disappears completely, we will have to go to a hair graft to recover the hair.

Diffuse alopecia causes the patient to lose a lot of hair in a short time. The lack of density does not occur in the frontal and crown of the head as it occurs in cases of androgenic alopecia, but in a generalized way. 

alopecia areata

In the case of the alopecia areata hair loss is irregular. This means that we will see bald spots on the scalp without any apparent order and, usually, in the form of round patches.

Alopecia areata is of autoimmune origin, that is, it is the person's own immune system that attacks hair follicles randomly, causing irreversible hair loss. 

alopecia nervosa

There are certain types of alopecia that are temporary, and that is what happens with the nervous alopecia. This type occurs precisely due to factors such as stress, nerves or anxiety. It does not usually generate bald spots, but the patient does experience a lack of density and intense hair loss. 

Normally it should not worry us, because it is a type of temporary alopecia. Of course, it can serve as an incentive to cause other types of alopecia that were latent.

La eating It is also a factor that influences the state of our hair; a bad diet can aggravate hair loss.

Traumatic alopecia

Finally, in this list of types of alopecia we want to talk about traumatic alopecia. This type is also usually temporary, produced by a situation that causes the hair to fall out, such as bad discoloration. 

Treatments to stop hair loss

scarring alopecia

Scarring alopecias are those that generate scar tissue on the scalp, that is, it leads to the appearance of scars. They are not usually the most common types of alopecia, although they are somewhat more complex to treat. 

Fibrosing frontal alopecia

La fibrosing frontal alopecia It is thought to be autoimmune and hormonal in origin, which implies that the patient's immune system destroys the hair follicles, leaving a scar. It mainly causes a receding in the frontal hairline, that is, the hairline begins further and further back. The patient may even experience a lack of density in the eyebrows. 

Lichen planus

Lichen planus leads to irreversible hair loss due to the accumulation of keratin on the scalp. It is not known exactly what causes this type of scarring alopecia, although it is thought that taking certain medications or suffering from certain diseases may influence it. 

Flat lichen produces symptoms such as itchy scalp, crusting, and patchy hair loss. 

folliculitis decalvans 

La folliculitis decalvans leads to the appearance of pustules on the scalp. This causes the hair follicles to become inflamed and shed, so the hair that falls out will not grow back. It can also cause itchy head and redness of the scalp. 

dicoid lupus 

Lupus is an autoimmune disease that affects tissues and, in many cases, can cause irreversible hair loss. In these cases, the patient experiences hair thinning and loss of hair density. In more advanced cases, bald patches with scar tissue develop.  

trauma scar 

It cannot be identified as a type of alopecia itself, but the appearance of scars from trauma, burns or previous surgeries cause areas without hair. No hair will grow back into that scar tissue.

The importance of a hair diagnosis

It is really important to request a medical diagnosis before the effects of alopecia are greater. Thanks to this process, it is possible to analyze each case in a personalized way to see which solution is the most effective.

Among other things, this diagnosis analyzes these three points:

Study the degree of alopecia

It is important to analyze the progress of alopecia, seeing what is the degree of lack of density that there is to see how much it is necessary to cover and if the donor zone It arrives to cover it in case of capillary graft.

Analyze the type of alopecia

Among other factors to analyze prior to the hair implant, it is also necessary to see the type of alopecia present so that it can be seen if it is operable or not, depending on, for example, if it is a type of autoimmune alopecia.

In addition, it is important to determine the type of alopecia to recommend the most effective hair treatment in each case. It is normally used hair mesotherapy and the Platelet Rich Plasma to stop hair loss, especially in cases of androgenic alopecia or telogen effluvium

See hair quality

It is also important to see the quality of our hair, since it significantly influences the visual sensation that we are going to have with the hair. hair transplant result.
