Developer was too weak

Developer was too strong

Look at the undertones in the hair colorbefore applying. Blue undertones willreact with yellow/gold tones in hair

and turn it green.

Ash toners have blue/greenpigments that will mix with yellowundertones and turn the hair green.

A large build-up of dye from pasttreatments can make it difficult forbleach to penetrate the hair cuticle

and remove color.

PROBLEM EXPLANATION & SOLUTIONCAUSE

Why is the hairdye not sticking

to my hair?

Why did my haircome out yellowafter bleaching?

Hair was too porous

Hair was too greasy

Used incorrect hair dye

Did not use enoughdeveloper

Hair was too clean/freshlywashed prior to bleaching it

Bleach was left on scalptoo long

Bleach was too weak

Bleach was rinsed tooearly

Hair has been excessivelychemically processed

-Use a cuticle repairing,or protein rich oil for

healthy hair.

Heated, hairstyling toolsand chemical processes

create porous hair that doesnot take color well.

Heads produce natural oilsthat protect the scalp from

harsh chemicals. Too much oilwill make hair color slip off.

-Choose toners or dyewith warm undertones

(like red or pink) tocancel out the green

tones.

Bleach reacts with Developer tocreate oxidation and cause hair tolighten. Without the correct strengthor amount of developer, oxidation

will not properly occur.

-Although a certain amount ofhair oil is good for growing andrepairing healthy hair, avoidprocessing overly-oily hair.

-Use a stronger developersuch as 30 or 40 volume.

-Carefully read theinstructions and mixing ratio

on bleach pack beforeproceeding.

-Use a high quality hair colorremover or clarifying shampooto get rid of excess color and

make bleaching easier.

Heads produce natural oils thatprotect the scalp from harsh

chemicals. Freshly washed hair willbe missing this barrier.

-Avoid shampooing hair 1-2days before bleaching.

Developers with greater volume (30or 40) are harsher on the skin and

more likely to burn the scalp. -Use a lighter developer

such as 20 volume.

-Set a timer and makesure the bleach is not lefton the scalp for too long.

-Check on the hair'slightening progress often.

Bleach was left on scalp toolong

-Set a timer and make sure thebleach is not left on the scalp

too long.

Bleaching is a harsh process thatstrips away nutrients and moisturefrom hair. Loss of hair's structuralintegrity leads to a fragile and

exposed hair cuticle that clings towater in an attempt to regain lostmoisture. The hair will become

overhydrated and develop a gummytexture.

-Wash hair as little aspossible with gentle, sulfate-

free shampoo.

-Use nourishing products that help safely regain hydration.

Bleach takes time to properly takeeffect, rinsing it off too early mayleave behind the hair's natural

yellow undertones.

Weaker bleaching products may notcompletely remove color even if left for

the appropriate amount of time.

-Carefully read instructions onbleach pack and allow productto sit on hair for the correct

amount of time.

-Research hair productsbefore purchasing andlearn which is right for

your hair type.
