Subject: Tinted hair
Hi David, I have been using your Psorexederm Scalp treatment
for my Seborrheic Dermatitis and already have noticed very positive
results after less than a week.
I am due to have my hair coloured in 4 weeks
time and wonder what your thoughts are on the relationship between colouring
products and my skin problem - do you think colouring my hair could contribute
to my skin condition? - VIC, Australia

ANSWER: Do you think colouring my hair could contribute to my Seborrheic Dermatitis scalp condition?
Hair and skin conditions such as eczema, sebborheic dermatitis and psoriasis may be aggravated by these products.
Applied to a normal scalp they rarely cause problems.
A damaged scalp is much more sensitive to Hair chemicals.
Hair Dyes are 2 pack products that when mixed together lock the dye into the hair and also the skin of the scalp.
Hair tints are usually one pack products that last several washes. These are quite mild and do not often cause problems
Hair perms have 2 packs which first break the bonds holding hair molecules together then a second pack to reform the bonds when the hair is in place. This locks the hair into a "Perm"
as people with perms usually wash their hair infrequently, the perm itself usually isn't a problem but the scalp should be washed at least 3-4 times a week to remove oil ,scale and as good hygiene.
Salon Dye and Perm products are the strongest and thus can worsen the scalp problem the most if you are sensitive to the chemicals in them.
Do-it-yourself kits contain lower strengths of the same substances as salon products.
Tints are a one pack product that coats the hair for 1-2 washes and cause less scalp problems but require frequent washing and application.
Lead containing products to turn grey hair to a dark color slowly are such brands as "Grecian" they usually
contain lead acetate and sulphur. Although I believe lead products should be avoided due to the toxicity of lead,
I have rarely seen these products cause problems.
The problem is traces of dye or perm chemicals remain in the hair and scalp longer than after the color (or Perm) has disappeared.
If you suspect a product is aggravating you condition you should allow the product to grow out and assist removal of the chemicals from your scalp by frequent washing.
HOW TO QUICKLY TELL IF YOUR HAIR PRODUCT IS AGGRAVATING YOUR SCALP OR SKIN PROBLEM
Usually if a hair product is causing or aggravating your scalp it will show up as a definite margin between the good skin and the treated skin.
If the problem stops at the margin between your hair & bare skin then very likely your hair product is aggravating or causing your problems.
Also the problem may be uniform across the whole dyed area of you scalp.
You may need to wait up to a month after stopping the product for your scalp to recover.
CAN I USE NATURAL PRODUCTS LIKE HENNA INSTEAD?
Henna is a natural product which is a permanent color.The active ingredient binds into the hair coloring it and is very unlikely to cause allergy. It also has a hair conditioning effect.
Problems with Henna
As Henna permanently binds to the hair it will react with other hair colors applied later to produce unpredictable results.
Curling and perms cannot be applied to henna treated hair due to problems with breakage and unpredictable reactions with other Salon chemical treatments.
COMPATIBILITY OF OUR PRODUCTS WITH THESE HAIR CHEMICALS
Our Psorexederm scalp lotion is compatible with all the above treatments. Tar based shampoos like Sebitar and T-gel are also suitable.
Simply wash the product out of you hair the day before you visit the salon.
These are a safe class of product, the more permanent ones containing chemicals like Hydroxyacetone. Rarely do they cause allergy and if they do it will only be in the areas they were applied.
Simply take a non-sedating antihistamine such as Claratyne and use our Psorexederm for the itch. The problem will resolve is several weeks. This is one condition where a short course of mild cortisone cream may also be beneficial without causing harm.
I SUSPECT MY HAIR PRODUCT IS CAUSING OR WORSENING MY SCALP CONDITION, WHAT CAN I DO?
If you can, stop using the product for 1 month then start using it again. If your product is causing problems your scalp will improve during the month you are not using it then the problem will worsen when you restart it.
This procedure is often medically used to test for true sensitivities and is called rechallenge.
MY HAIR PRODUCT IS CAUSING PROBLEMS,WHAT CAN I DO ?
Stop using the product.
If you must use a hair dye/tint e.t.c find out the concentration and names of the active ingredients in the one you have problems with. Try to find a different product with different ingredients.
This is often hard to do as many formulas contain the same chemicals.
Find a product with a lower concentrations of the ingredients, you may find a threshold below which your hair is fine and your scalp gets better.
If that fails use a one part tint and redo the color more often.
Above all, try to wash your hair 3-4 times a week or more. Twice a week and you will get scale build up.
As a Dermatologist once told me, you wash your body each day and you should wash your hair each day.
I know this isn't practical for all people so juggle it to suit.
