What determines different hair types and textures?
Like most things in life, and with your physical traits, you can thank your parents. Genetics plays the biggest role in life in terms of our appearance, including our hairstyle and texture.
While genetics is the biggest determinant of the type of hair we inherit, there are several other factors that need to be considered. Some medications can affect hair texture and can even make your hair frizzy!
Hormones can affect hair growth through major changes like pregnancy or menopause. Chemicals used to style your hair, such as perms, can cause changes to your hair. Finally, age can lead to changes in your hair, such as graying, which can change the texture, density, and thickness of your hair.
What is my hairstyle?
Finding your hair type is simple enough. You can easily determine your hair type by whether it is straight, wavy, curly or curly without styling or using any products. 
Straight hair has no curls and is, as the name suggests, straight as a stick. Wavy hair has very loose S-curls. Curly hair has well-defined loops and circles. African curls are curls that are tighter and will have more volume.
If you want to dig deeper and understand your hair texture, once you've found your hair type, you can consider one of the three texture possibilities outlined above. Take a strand of hair and rub it between your fingers.
If your hair feels thinner than the thread (or not even noticeable), you have fine hair (type A). If you can feel your hair, you are probably medium hair (type B). If the hair between your fingers feels very thick, you have coarse hair (type C).
How To Take Care Of Aging Curly And Wavy Hair 
Keeping curls and waves healthy as you age is easy and requires only a few considerations.
Washing your hair as needed is a great way to keep your hair clean and prevent it from drying out. Frequent shampooing can strip your hair of moisture and irritate your scalp. Washing your hair periodically or less often is a great way to keep your hair healthy and prevent it from drying out.
Moisturizing is an important aspect of wavy and curly hair care. Use products that provide good moisture to the hair shaft through the hair shaft and hair follicles.

How to take care of straight hair when aging?
Straight hair can be a little easier to recover from damage than most other hair types (such as using a hair dryer). But elastic hair still needs care, especially aging straight hair. 
The downside of straight hair is that it will lose thickness and become thinner, especially if you already have thin hair. Check out the Nubeà Sustenia range of shampoos and conditioners for volume.
