Let's start the training with a few basic elements.
To determine your curl type, you need to assess the texture, shape, thickness level, and shrinkage potential of your hair. You should also pay attention to your hair type, whether it is oily or dry, so you can decide which products will work best.

The 12 hair types, as defined by Andre Walker, hairstylist of Oprah Winfrey, in 1990. Initially, the chart was created by him for the launch of his products in the market but has since been widely used as a classification chart for hair.
Hair typing is a starting point, an easy way to begin navigating through the many product and styling options; essentially, it is a reference guide, not a way to separate people into different groups. Since we deal with curls, we will lovingly and respectfully bid farewell to category 1 from this blog and start our journey from category 2.
Type 2a

Slightly 'S'-wavy hair that lies close to the head and tends to have fine density. This hair type dries quickly and straightens easily and is generally quite low maintenance. To maintain 2a hair, skip heavy products as they can weigh the hair down. To enhance your texture, sea salt sprays work particularly well.
Type 2b

The wave usually forms along the hair in an 'S' shape like in Type 2a, but the hair lies closer to the head. Type 2b waves may be slightly fluffier at the top of the head and tend to lose curl definition easily.
If you have 2a and 2b hair, you should focus on enhancing volume and texture using a root-boosting spray and a texture spray.
Type 2c

These waves are the wildest - coarsest of the wavy hair patterns. They consist of a few more actual curls, unlike simple waves. To care for 2c hair, reduce frequent washing (or use a very gentle moisturizing shampoo without sulfates if you need to wash more often), use a lightweight curl serum to encourage the curl pattern, and sleep on a silk pillowcase to avoid frizz and tangling.
I would say that 2c waves are a bit denser and tend to be a bit frizzier. The use of a moisturizing conditioner or mask is essential.
