If, at any time during the test period, there is any burning, itching, swelling, irritation, eruption, or any other abnormal reaction or aware ness of sensation in or around the test area, then the person is allergic or predisposed to the preparation and must not use it.
Because there is no adequate or satisfactory method of predetermin ing the presence of hypersensitivity of the more delicate orbital areas or optic tissues, permanent haircoloring must not be used on eyelashes or eyebrows.
If a woman is found to be allergic to one product, this does not neces sarily mean that she is allergic to all haircoloring products. For example, a person who is allergic to Hair Tint X has subsequently been given a patch test with Clairol Salon Formula Oil Shampoo Tint and then found, in this case, to be non-allergic to this tint.
PREPARE TINT MIXTURE FOR PATCH TEST
Mix 6 drops of color or mixture of colors to be used with an equal amount of Clairoxide or Pure White Creme Developer.
HOW TO GIVE A PATCH TEST.
Patch Test Must Be Given 24 Hours Before Each Application.
1. Thoroughly wash a small section behind patron's ear with mild soap and water.
2. Apply tint mixture to washed spot. Leave wet. If patron reports no sensitivity or reaction within 24 hours she may be considered non-allergic.
3. You may use inside elbow in stead of ear as test area if you prefer.
PREVIEW YOUR COLOR SELECTION
Before the application of tints or bleaches, it is advisable to preview their effect by giving a Preliminary Strand Test.
THIS STRAND TEST WILL HELP YOU DETERMINE THE FOLLOWING:
- Whether proper color selection has been made.
- The proper length of time to leave the bleach or tint on the hair.
- Whether the hair has been previously treated with either a perma
nent wave, bleach, tint, metallic dye, compound henna, or rinse.
Thus you will foresee any possibility of breakage or discoloration.
When any of these conditions is evident, do not tint or bleach
without first reconditioning and then retesting the hair.
- If the general condition of the hair is not good, the test will show
where porous areas exist and enable you to foresee unsatisfactory
results such as streaked or dark ends.
A PRELIMINARY STRAND TEST IS GIVEN IN THE FOLLOWING MANNER:
- If tint is used, mix a small amount of equal parts of the color or
colors selected and Clairoxide or Pure White Creme Developer.
If a bleach is used, mix 1 part bleach with 2 parts Clairoxide or
Pure White Creme Developer. For exact proportions, check direc
tions which come with the product.
- Apply the mixture to a full strand of hair and allow it to develop
until the desired shade has been reached.
- Wash and dry the test strand and examine results. If the results
are satisfactory, proceed with entire treatment.
In tinting, if color is almost correct, leave on longer for a deeper shade; less time for a lighter shade. But if the color is very different from the shade desired, select another color and make another Strand Test.
In bleaching, if the test strand is too dark, this indicates that, in your regular application, the bleach should be kept on the hair longer. If the test strand is too light, then less time is needed.
When discoloration in the Strand Test indicates the presence of for
eign elements, corrective steps must be taken. For specific directions,
see chapter 15—"Reconditioning Hair," and "110 Professional Case
Histories" ......... The "1-20" Test, Page 157.
