The treatment will not be as dark after your first shower after four days from your treatment.
Same after your second treatment. It’s quite dark until you have your first shower and shave after four days.
The treatment will settle down after about four weeks.
I kept my original hairline as I’m 54.
Wait until after your second treatment has settled a while before you consider altering your hairline.
Best thing I ever did to be honest I love it.
Had mine done last September at Manchester.
Hope this helps.
