A visit to the barber shop can be an undesirable trip for preschoolers. Sharp objects buzzing beside thier ears and coming close to their head can be scary and intimidating. To ease their fears, try showing an educational video of a favorite character talking about the importance of getting a haircut, as well as hair care and styling. After the video, have students talk about their experiences at the barber shop. Put together a kit containing barber shop items -- clippers, brush, scissors -- and allow children to play with the items in dramatic play. Also, the word "trim" may be more palatable than "haircut" when describing the procedure.
Red eyes and tears are no longer synonymous with washing children's hair. With so many mild, natural ingredient based products on the market, hair washing can be a fun bath-time experience. Talk to the students about the importance of washing their hair often, and discuss easily communicable childhood conditions like head lice, a bug infestation of the scalp. Tell the students about treatment plans, such as the use of permethrin cream rinse, which can be purchased over-the counter. Do a demonstration of items that need to be thoroughly disinfected like clothing, bedding, and hairbrushes or combs. Coincide your head lice lesson with a school nurse screening of your students.

Help them associate the connection between how their hair looks and that of their family members to relate to study of genetics. Chart their comparison on a graph showing the lineage of their hair type or create a class hair book.
