Which is better for covering gray hair?

The L'Oréal Paris Superior Preference states 100% gray coverage and gives a processing time for gray hair. The IGK kit says it covers gray but gives no percentage.

Is the IGK kit worth the extra cost?

Only if you want its ammonia-free, fragrance-free formula and extra kit items like barrier gel and stain cleanser. Otherwise the L'Oréal kit does more for about $18 less.

L'Oréal states up to 9 weeks of fade-defying color. IGK calls its color permanent but gives no fade timeline, so L'Oréal makes the stronger claim.

Can either one lighten my hair?

No. The IGK kit will not lighten previously colored hair, and L'Oréal Superior Preference is a color deposit, not a lightener.

Which is better for sensitive scalps?

The IGK kit is fragrance-free and ammonia-free, which may suit sensitive scalps better. L'Oréal is ammonia-free but has a floral scent.

How many applications does each kit give?

The IGK kit is listed as one application, sized for long or thick hair. The L'Oréal kit is a single full-coverage application.
