At-home hair gloss, a type of cosmetic hair product, is a semi-permanent hair color designed to enhance natural hair color and add shine, like a L'Oral Paris Hair Gloss.
This popular hair treatment, often used as an alternative to traditional hair dyes, offers vibrant color and deep conditioning, leaving hair feeling silky and looking healthier. The development of ammonia-free glosses in the 1980s significantly reduced potential hair damage, making this beauty treatment more accessible.
