Ruling out allergic reactions which can be serious in some people.
I totter off to the local Superdrugs every month or so and pick up a pack of their hairdye (or two if it's on a special offer).
No real science behind my choice I have to say, I buy a blonde~ish one (currantly 10.00 and 10.0. There is a difference but I'm darned if I know what)
DD was helping me get the bits at the back saying "Why don;t you go to a salon for this?".
Well, in no particular order:
I am exceptionally tightfisted. I don't want to spend £40 when I can do my own.
I don't like having my scalp touched (even having it cut makes me wince)
I don't do planning with my hair. I like to wake up and think "Haircut" or "Dye".
It needs cut every 5-6 weeks , dye every 3 weeks.
I am getting bored with it a bit but I don't want to go darker . If I put a wash in over my dyed hair what;ll happen?
For example, a wash in red on my dyed copper.
Will it go pink? Green?
I'll do a patch test of course but I don't do a strand test .
I appreciate the £££ spent at a salon is for their skill and experience (of which I have neither) but I have very short hair so any cock ups , I can crop out.
