L'Oréal Paris Men Expert Shirt Protect 48H Anti-Perspirant Deodorant is designed to help keep you dry and to help protect your shirts from deodorant marks. The brand says it targets four types of mark: sweat patches, yellow stains, white marks and the 'cardboard effect', where fabric stiffens after washing.

It uses an ultra-absorbent Active Micro Captor to help combat wetness. Anti-yellow stain technology helps protect clothes from yellowing, and anti-white mark technology helps fight white residue and dust. The formula also helps avoid the deposits that stiffen fabric after washing, drying and ironing. In instrumental tests it gave a 48-hour dry non-stop effect, and it has a long-lasting fresh fragrance.

Shake well, hold the can 15cm from your underarm and spray. It is an extremely flammable aerosol, so keep it away from heat and flames. Do not spray it towards your eyes or on irritated skin.
