There are many different scalp disorders out there – some more common than others – that can affect the health of your scalp and the way your hair grows.
One condition that can affect many people is Pityriasis Amiantacea. If you’re worried about whether you might be experiencing this, or would like to know more about the condition, keep on reading.
Pityriasis amiantacea (also known as tinea amiantacea) is a scalp condition where there is excessive scaling across the scalp. It can be an uncomfortable confidence-crushing condition that can appear in patches anywhere across your scalp.
They will most commonly look like thick, silver or yellow scales that completely surround the hair shafts around the scalp and can start to ‘stick’ clumps of your hair together.
Pityriasis amiantacea is defined as an inflammatory disease or an eczematous condition that can be quite troublesome and stressful for the person who is suffering from it.
Some of the most common symptoms of this condition include:
If you’re noticing any of these symptoms, we’d suggest visiting your GP as the first port of call as they will be able to help identify your condition and discover what the underlying cause may be.
Pityriasis amiantacea is usually a reactive condition, rather than a diagnosis. It’s normally associated with an underlying skin condition such as:
One study  found that psoriasis accounted for 35.3% of pityriasis amiantacea cases; aggregated seborrheic dermatitis and atopic eczema for 34.2%; and tinea capitis for 12.9% of cases.
Similarly, in a study of 59 patients  it was found that 15% had suffered from psoriasis, and 19% were aware of psoriasis in their relatives, proving that this is another common condition that can result in pityriasis amiantacea.
Just because you are experiencing one of these conditions, it doesn’t automatically mean that you will also suffer from pityriasis amiantacea as it’s not prevalent in all cases.
However, if there is no specific underlying cause that has brought on this condition, you may hear it referred to as idiopathic pityriasis amiantacea.
Although there is not a lot of frequency data that can suggest how many people are affected by this condition, some studies have found a possibility that some patients present some sort of genetic or environmental predisposition more than others [3,4].
Children are far more likely to be affected by pityriasis amiantacea, although it is possible for the condition to occur at any age .
Although the condition is relatively rare, the condition is more common in females than it is in males. One study found that the prevalence of male to female was 1:1.6  with a mean age of 42.4±23.4 years.
The treatment of pityriasis amiantacea will largely come down to the underlying disease. So it’s important to discover the cause before you start looking into different treatment options.
Some of the most common treatments for pityriasis amiantacea include:
In one study, patients were given topical ketoconazole, which is a treatment usually administered for fungal skin infections and dandruff. With daily application of a 2% strength shampoo, all patients were able to treat their pityriasis amiantacea within 6.4 months, on average .
Most patients often respond well to the range of treatments that are listed above, especially when they are administered in accordance with underlying conditions. For those who don’t notice any positive changes, or who experience side effects from taking treatment, scales can also be removed by surgical scissors .
Pityriasis amiantacea can cause temporary hair loss in some patients during certain treatments, especially when the crust is being removed from the hair follicles. However, there is still a lack of frequency data that shows how common hair loss is in patients with this condition.
The hair loss is normally temporary and will continue to grow back as normal once treatment for the condition has finished. However, hair loss may make the condition even more stressful for patients.
If you are suffering from temporary alopecia due to treatment for your condition, there are a few different ways that you can combat this. You may choose to take oral tablets, such as Finasteride and Dutasteride, or topical treatments such as Minoxidil.
However, it’s very important that if you are thinking about taking any hair loss medication you consult your GP first to ensure that these treatments won’t have any negative effects.
Hair loss is something that happens to many men and women every year, and in many cases, it is completely treatable – either through medication or something more permanent like a hair transplant.
If you’re worried about losing your hair due to pityriasis amiantacea, it shouldn’t be such a big cause of concern as this is normally a temporary side effect.
