L'Oréal Sued By Customer Who Claims Product Burned Her Bald

L'Oréal's got another angry customer ... and she says SHE has PHOTOGRAPHIC evidence the company burned her bald. 

L'Oréal's pushing a hair relaxer called SoftSheen-Carson Optimum Amla Legend No-Mix, No-Lye Relaxer. Delicia Taylor says in a new lawsuit she relied on the promise she'd get fuller, silkier hair.

So imagine her dismay when she looked in the mirror to see bald spots, burns, blistering and scabs on her scalp ... this according to legal docs obtained by TMZ.

We broke the story ... L'Oréal was sued back in September when a group of angry customers made similar allegations ... this after L'Oréal got a bunch of celebrities to tout the product. 

Taylor's suing on behalf of all women allegedly burned for more than $5 million in damages. Why? Because they're worth it.
