How long do we avoid shampoo and shower gel that are perfume based after rads?

Hi I am just about to have my last 4 of 28 rads this week and have been using Johnson’s baby bath for washing all over. Can anyone advise me how long after finishing rads we can use perfumed products again?

I finished last Friday. I was told to avoid perfumed lotions, shower gels for a month to allow skin to heal. I noticed today that my nipple has crusted up and started peeling yuk very unattractive!
