YES. You cannot practice legally without a license. The state-certified license of a Barbering/cosmetologist takes time to earn and practitioners of the craft may be eager to get started, but they cannot practice Barbering/cosmetology without a license. By law, any services done within the field of Barber/cosmetology for any form of compensation is illegal if done without a completed education and a license.
The size of the fine depends on the kind of activity you engaged in and the laws of your state. Common fines for misdemeanor offenses range from about$500 to $1,000 or more.
