wash 1-3 times a week and you want to use fingertips to massage deeply not scratch, massage
if you wash whenever it starts to itch you won't have to scratch
its going to take months
timeline
it takes about 3 months to recover from each time you retwisted if you retwisted each time it recovered, or sooner, before it could recover it will only get worse..so your looking at about 3 months for the most recently affected areas to recover and 6 or more for the areas that have been suffering the longest to recover
its hard to give exacts but i have seen way worse then this almost fully recover in a year so im guessing 6 or so months should be enough to be back to healthy
