If a teenage girl only showers every second day, she smells, and her hair probably smells too.
The increased smell of teens is a well known effect of puberty. I don't know why there are posters here who refuse to accept this basic and well observed fact.
Teens do not smell like fields of daisies or two week old babies.
Teen sweat contains aldehydes, steroids specific to pubescent and adolescents, and carboxylic acids. These chemicals are described as smelling of urine, musk, sandalwood, goats, cheese, and wax. Teens produce more of these chemicals than children and most adults, and they also produce more sebum than pre pubescent children and adults. The longer the sweat sits in the undisturbed sebum (oil), with bacteria attacking it as it sits, the stronger the stench. Bacteria work on sebum amd sweat all over the body. In the case of this teen, deodorant and body spray are added to the mix. The result is stench.
In plain language, teens need to shower daily.
In the case of this teen, deodorant and body spray, stale and fresh, are added to the mix. Other people have the right not to have to sit in a stuffy classroom near someone who last washed more than 24 hours previously, and is wearing the same shirt she wore yesterday or one that might have sat in a laundry basket with socks and underwear and damp towels since Monday. Even if a previously worn shirt has been hung up, it will smell.
