A few years ago I used to box colour my hair at home (just using Nice & Easy to cover greys!). I’m classic mousey brown but have a lot of warmth so always need an ash tone as I hate my warmth (always looks orange to me 🙁). I’ve been having a ‘glossing’ treatment every 8wks to cover the grey & tone down warmth but it never stays for long so I’m considering going back to doing it myself (plus cheaper). What brand etc would you recommend to knock out the warmth & cover the greys?! Thanks 🙏 n advance :)
