For one, the odorants used in functional perfumery (i.e. for fragrancing cleaning products, car seats, air fresheners, what have you, as well as beauty products) are today frequently the same as those used in "high" perfumery. So you might rediscover the fragrance complex, or parts of it, of your $2.99 shampoo in a $79.99 perfume. The other aspect is the popularity since the 1990s of so-called aquatic / marine / ozonic notes in perfumes, which are also standards in shower gels, shampoos etc. to suggest freshness and cleanness. Calone and Dihydromyrcenol are two synthetic odorant particularly responsible for much of this.
