Cosmetology

Cosmetology is a talent badge from Open for Business. With the Ug-No-More Makeover Chair, a Sim can give makeovers to other Sims. A Sim's Cosmetology level determines how likely they are to do a successful Makeover. Also, as a Sim's badge level increases, the animations will change to reflect the Sim's increasing skill. High cleaning skill helps gain cosmetology badges.

No badge
High chance of messing up the makeover.

Bronze
Medium chance of messing up the makeover.

Silver
Low chance of messing up the makeover.

Gold
Very low chance of messing up the makeover.

Positive effect
A successful makeover opens the "Change Appearance" options screen. Here the player can change the appearance of the Sim who had the makeover. The customer will be pleased and, if it was not offered for free, pay for the makeover.

Negative effect
An unsuccessful makeover displeases the customer and their appearance is changed, usually by receiving a weird haircut or full face makeup. The Sim who did the makeover still gets paid, unless it was a free makeover.

For selectable Sims, this can be undone by using the Change Appearance option on a mirror. For others, it can be undone with the makeover chair. (It may be necessary to apply full face makeup in order to be able to use the option to remove all full face makeup.)
