I have not colored my hair in a few yrs, and since i'v only had parrots for the past 8 mos, well u get the picture. I'm wicked board of my color, and wanna change!!! my Spartacus LOVES to preen hair though...what do to?!? can I still do it & just try to keep him away from my hair for a couple days?? or forever? seriously I NEVER use hair product ( shampoo /condiner) ...I would imagine it's bad for them, but how bad? how long till he could preen my hair?
I am not an expert, but, the shampoo etc is something Ive thought about as well.
Because of it, we only use eco-friendly, perfume free, and allergy-approved shampoo, conditioner and soap. Its the "nicest" shampoo you'll find and I think its awesome, and my scalp itches less as well, so its good for me too.
I dont know much about hair colouring ^^, but I dont think its an issue, (maybe dont do it at home though for potential fumes?), and be sure to wash your hair many times afterwards, with shampoo

. Keep your bird away from your hair for a few days, and be sure to rinse it lots and lots. I cant see how it could be an issue if you do that,
but I'd hold off until someone more knowledgable about haircolouring etc gives you a reply ^^!
