After a client’s first waxing, the results can last 3 to 6 weeks depending on the individual’s hair re-growth rate. In most cases, hair growth is minimal during the first week or two and noticeably increases in the third and fourth week. Heat stimulates hair growth; therefore hair grows quicker in the summer than in the winter. With regular waxing the length of time between treatments will increase. Continued waxing results in sparse hair re-growth.
