Procedure for preliminary test curls

Taking preliminary test curls help you predict how your client’s hair will react to a perm. If is advisable to take preliminary test curls if the hair is damaged or if there is any uncertainty about the result. Preliminary test curls provide the following information;

• Correct processing time for optimal end development
• Result you can expect from the type of perm solution you have selected
• Curl results for the tool size and wrapping techniques you use planning to use.

Procedure:

1.Wrap one tool in each different area of the head (the top, the side, and the nape).

2.Wrap a coil of cotton around each tool

3.Apply waving lotion to the wrapped curls. Do not allow waving lotion to come into contact with unwrapped hair.

4.Set a timer and process according to the manufacture directions.

5.Check each test curl frequently for proper curl development. Unfasten the tool and unwind the curl about 1.5 turn of the tool. Do not allow the hair to become loose or completely unwound. Gently move the tool toward the scalp to encourage the hair to fall loosely into the pattern.

6.Curl development is complete when a firm and definite “S” is formed that reflects the size of the tool used. Different hair textures will have slightly different “S” formations. The wave pattern for fine, thine hair may be weak, with little definition. The wave pattern for coarse, thick hair is usually stronger and better defined.

7.When the curl has been formed, rinse thoroughly with warm water for at least five minutes, blot thoroughly, apply neutralizer, and process according to the manufactures directions. Gently dry the hair and evaluate the results. Do not proceed with the permanent if the test curls are extremely damaged or over processed. If the test curl result are satisfactory, proceed with the perm, but DO NOT re-perm these preliminary test curl
