Managed through a series of home routines that become part of your daily stuff like washing your teeth.

Buy the following :-
1. a long handled stiff back brush
2.a soft sponge
3. a bundle of flannels
4. bottle of tea tree essential oil and a bottle of rosemary essential oil
5. a tube of quinoderm cream
6. a good quality non-laureth sulphate shower gel

DO NOT USE SOAP

OK off we go

MORNING routine
————————–
Shower or bath every morning whether or not you think you need it
Scrub your back every time using the shower gel
You must dry your back immediately and properly till bone dry
Apply quinodern topically to the worst areas, this will help stop infection on broken skin

BATH routine
——————-
Bath with a few drops (7 max) of essential oil added to the water
It is very potent so you have been warned, Use them alternatively.They have anti-bac and anti-viral properties.
Scrub your back
Dry properly
Apply quinoderm topically
Use flannels dipped in water with ess oils to treat any inflamed areas.
Keep your towels and flannels scrupulously clean and fresh
Don’t use soap as it builds up on skin and layers leaving fatty deposit and scumy residues.
After a bath rinse off the unclean water you’ve been sitting in with a hose down of fresh cooler water, this will clean you down and close the pores a bit.
Scrub out the bath after every use

Change your t-shirts every day/twice if you need to
Change bed linen every 5 days
Change pyjamas every day/other day

Drink an extra litre of water a day till you are peeing once an hour,increase uptake on fruit the 2 that help are grapes and pears.

Its an effort upfront but oh the difference after a few weeks and manageable thereafter.

Best Wishes
