many products are made for ang mo..
Like Redken glosser (hair color).... is made more for ang mo cos their hair is not shiny like asian hair.
Like the sea salt spray and other pre style products are meant for fine hair to give that lift and volume, for curly hair to give body. Again, it is meant more for ang mo cos their hair is fine and limp, generally asians (not all of cos) have thicker hair so it may not be necessary. So if you have short, thick hair... you don't need a pre style product.
When your hair is
fine, it means that the diameter of your hair is smaller and "thin" refers to not having a lot of hair. When your hair is
thick, it means you generally have a lot of hair and the diameter of the individual hair strands tends to be generally larger too, but not always. In some cases, its not surprising to have fine and thick hair too.
I would beg to differ on the usage of SSS. Many people mistake the point of having thicker hair to having volume.
Case #1: Thick hair (Lots of hair and thick hair diameter)
When your hair is thick, yes its true that you have a lot of them. People with thick hair go well with any kind of styling products. Proximity of hair growth is high and you will appear to have a lot of hair. People in this category is unlikely to escape from the term "coarse". However, this doesnt mean you have volume too. There are several factors coming into play.
Type 1: Thick and full but not voluminous (pong). This means that your hair has more weight which leads to heaviness. When its heavy, it tends to be lying down due to gravitational force and it will naturally fall flat. So when its flat, there is naturally no volume. People of this type can use SSS too. I myself am in this category. When my hair is dry, its totally flat and there is no volume but there is fullness. So i use SSS to create the volume to complement my already in-place fullness to look even better.
Type 2: Thick and full and voluminous (pong). This means that you got the volume already. Your hair is often sticking out and is almost never flat. It can be said to be untamed too. You often find yourself having to shave the sides very often. People in this category do not see the need to use SSS which is legit as they do not require the volume at all. However, a regular and good haircut is often required to control it well.
Case #2: Fine and thick hair (Lots of hair and small hair diameter)
When your hair is fine and thick, you have lots of them but the diameter is small. In this case, your hair will appear to look soft and having good hair texture. IMO, people who are in this category will look great with their hairstyle and portray a healthy outlook with well growth hair. With that said, SSS is also possible for people who falls into this category as it creates volume for you too.
Case #3: Fine and thin hair (Not much of hair and small hair diameter)
People often associate fine and thin together but they actually means different things. People in this category will benefit the most from using SSS as it will create a full and voluminous impression to others upon application of SSS.
Just stating my 2cents worth of opinions again. Because i recommend SSS to people with thick hair and similarly, it works well for them too. On a side note, I got a fren who dun need to style or do anything but his hair looks like a mane and totally untamed. So SSS will not work or is unnecessary for him in this case.
