just really repeating what every one else has stated, "ditto"!
transitioning to oneside*, when it takes longer to style youre hair using concealers then youve came to the end of the line and really need to make the change,
*cant really leave the transitioning stage @ that,
its kinda crucial to get it right, earlier so theres no major diffrence , ie somethings Diffrent between now and then,

dont keep relying on concealers,as a argument against wearing or putting the decision off,
take it from people who have been through the proccess,
take control of it, dont let it control you
