Psoriasis is a common skin condition affecting 2-3% of the population of the United Kingdom and Ireland.
Psoriasis is in simple terms only a vast acceleration of the usual replacement processes of the skin. It appears as raised red patches of skin covered with silvery scales.
With scalp psoriasis there is thick scale and redness that is also evident around the scalp margins. Many patients experience severe itching and a feeling of tightness and some report soreness. One patient has described the build-up of scales as being like 'a mountain on my head'.
For those with scalp patches which flare up from time to time it is possible to manage at home. Shampoo treatments are improving all the time and can be bought over the counter. Your pharmacist should be able to advise. However if your scalp is covered with thick scale or it does not clear up do consult your GP who may arrange referral to a Dermatologist.
There is a range of treatments which can be prescribed including coal tar, dithranol, salicylic acid, cortico-steroids and Vitamin D derivatives to bring the flare-up to a manageable level.
The method of applying the treatment is most important. It involves parting the hair in sections and rubbing the treatment along the exposed area. It is best to do this in a sequential fashion working your way around the hair. You may need someone to help you in order to see the top of your head properly.
Providing care is taken to avoid scratching the scalp, combing and brushing to remove scaling is not only good but necessary.
Scalp psoriasis should not prevent any cosmetic procedures. Having a perm or colouring the hair can have a positive effect on your self esteem. Hair dyes are gentler than they used to be but it would be best to seek advice from a hairdresser who should have up to date information about possible options rather than colour or tint your hair at home. It is also a good idea to make sure that there are no scratches on the scalp when the hair is treated as the chemicals concerned can cause irritation on the broken skin.
A good hairdresser should be able to help you manage your hair and scalp. Telephone in advance and speak to a stylist to explain the situation or try to find a hairdresser who will visit you in your home.
Some people with severe psoriasis suffer temporary thinning of the hair. This can be very distressing but the hair will grow again once the flare up has subsided.
Psoriasis is known as the waxing and waning condition, and it can and does go away. Some people may be lucky enough not to suffer a further flare up, others may experience long remissions. It is unusual for anyone to suffer extensive scalp psoriasis for a long time, provided they seek medical help and use treatments as directed.
