Buying Guide: Hair Dye
📋 Table of Contents
1What's the difference between permanent and semi-permanent hair dye?
Permanent dye uses ammonia to open the hair cuticle and deposit color deep inside, lasting until your hair grows out, while semi-permanent sits on the surface and fades gradually after 4-6 weeks. Choose permanent if you want lasting coverage or need to go significantly darker/lighter, and semi-permanent if you want to test a color or prefer less damage.
2How do I know if a dye will work on my current hair color?
Check the shade guide on the box—most brands show results on light, medium, and dark hair, so you can see what to expect. If your hair is very dark or previously dyed, you may need a lighter shade or developer with higher volume to achieve the desired result.
3What's the difference between developer volumes (10, 20, 30, 40)?
Higher volume developers process color faster and lift darker hair more dramatically, but they also cause more damage and dryness. Use 10-20 volume for root touch-ups or maintaining color, and 30-40 volume only if you're making a dramatic lightening change on healthy hair.
4Should I buy salon-quality dye or drugstore brands?
Drugstore dyes work fine for simple color maintenance, but salon brands offer better condition boosters and more nuanced shades if you're doing complex color work. Spend more if you have damaged hair, want precise results, or are making a drastic change.
5How much dye do I need for my hair length?
One standard box covers shoulder-length hair; if your hair is very long or thick, you may need 1.5 to 2 boxes to ensure full coverage. Check the bottle volume and your hair thickness before buying—it's better to have extra than run out mid-application.
