Amika
Amika is an American haircare brand whose products cover the usual shelf: cleansing shampoos, conditioners, masks and leave-ins, dry shampoo, styling products and heat protectants. It is widely stocked in salons and beauty retail, and its bright, colour-blocked packaging is much of how people recognise it.
Haircare belongs in a skincare glossary because it lands on skin. Shampoo runs over the forehead, hairline and back, conditioner residue can sit along the jaw, and the scalp is skin with the same barrier and microbiome concerns as the face. The surfactants that do the cleansing, the silicones and oils that condition, and above all the fragrance are the parts most likely to matter if your skin or scalp reacts.
So read a haircare label the way you would read a serum: check the ingredient list rather than the front of the bottle, patch test if you are fragrance-sensitive, and rinse hairline and back thoroughly. Persistent flaking, itching, redness or hair loss is a dermatologist's territory, not a product-swap exercise.
