It is important to be able to choose suitable hair curls for your customers’ wigs and hair replacement systems.   In order to choose a suitable type of curl for customers, you must understand the individual’s requirements and the curl standards of your current supplier.  Standards and professional curling techniques vary by supplier.  It is important to obtain a curl pattern chart from your vendor and have it on hand during client consultations.

Curls are divided into two categories:  NATURAL and CHEMICAL


Natural curls are created before the final packaging of the hair bundle or hairpiece. Natural curls are not permanent and will disappear once the hair is washed. Most hair vendors apply natural curls to hair to make the item look its absolute best before it is sent to the customer. 


Chemical curls are created by hair suppliers by following the sizes and patterns according to their curl pattern chart.  The curl pattern chart is specific to each vendor and is used as a reference for their services.  Curl pattern charts are also great to use during client consultations or before preparing to make a wig.

If you require a specific curl pattern, send a sample to your vendor and the pattern can be replicated to suit your requirements.

Silky straight hair is not the same as naturally straight. Silky straight hair will be chemically treated to become permanently straight.  Most often Chinese hair is used because the hair is already straight and therefore easier to process to a silky straight texture.

When you are choosing curls for your customers’ hair systems, we suggest weighing the hair because natural straight hair differs across different types of hair. For example, the natural curls in Chinese hair are very straight and sometimes there is virtually no curl. Indian hair has natural curls that may be bigger than 2.5cm. If a customer wants straight hair, but prefers to purchase natural Indian hair, you must explain the nature of Indian hair so that the customer understands that it comes with a natural curl.  If the natural curl of Indian hair is too big for your customers and they want straighter hair, you can suggest Chinese hair instead. However, if the customer insists on Indian hair and wants a straighter effect than what Indian hair offers, then chemicals can be used to soften the hair and loosen the curl. This process makes the hair straight as possible, but it cannot be curled later.

Hair curls less than 32mm must be achieved through chemical treatment or steam ironing. The smaller the curl, the longer it takes to process the hair with chemicals, and the more severe the hair damage. When your customers want a small curl less than 1.0mm, choose quality hair (such as Remy hair or Chinese Virgin hair) so that the texture of the hair will not incur much damage and the hairpiece will last longer. 

It is not recommended to add small curls to light-colored hair because light-colored hair is, in fact, dark-colored hair that has been dyed with chemicals…  Further chemical treatment to make the curls will significantly affect the hair quality. The end result will be rough, frizzy and fragile hair.
