Cosmetology

Cosmetology is a talent badge from Open for Business. With the Ug-No-More Makeover Station, a Sim can give makeovers to other Sims. A Sim's Cosmetology level determines how likely they are to give 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 in gaining cosmetology badge level.

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.

Sometimes, the customer might receive a successful makeover even if the change appearance screen doesn't appear, so basically they won't really receive a makeover at all, when this oddity occurs.

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.)

There is a mod which unlocks the hidden face makeup that Sims may get from an unsuccessful makeover. However it categorizes it as lipstick, instead of face makeup like the original.

Another mod exists that unlocks the hidden hairstyles that Sims may get from an unsuccessful makeover. Note that this mod does not unlock the electrocuted hairstyle.

The Ug-No-More Makeover Station
The Ug-No-More Makeover Station is found in the Comfort -> Misc. section of Buy mode, though it cannot be used as a chair. If used on an unowned community lot, it will spawn an NPC stylist, and the player will be able to either have the selected Sim get a makeover, or direct that Sim to give a Sim on the lot a free makeover.
