See, not everyone has thick hair. For some of us, fine or fine hair is a simple fact of life. Maybe you inherited good qualities from your parents (thank you mom and dad). Maybe you’re going through a stressful life and your hair is falling out. Whatever the reason, there are many reasons why strands are thin, flat, or thin. Cosmetic chemist Ginger King says “genetics, stress, poor nutrition, poor hair care and environmental damage (such as sunlight and rough brushing)” can all be potential causes of thinning hair.

However, there is some good news in the form of hair care products that will help plump up your hair, or at least make it look thicker and fuller than it actually is. As for what key ingredients to look out for when shopping for hair products, King recommends using polymers to “support” hair, while proteins “leave a coating” that gives the impression of thick hair.

King, on the other hand, says to avoid heavyweight oils and silicones because “not all oils or silicones are created equal,” adding that coconut and jojoba oils have a higher weight than other oils (replacing In other words, save jojoba oil for your skin-care routine.) Again, silicones vary in weight and grade. According to King, what’s the best way to test? “If your fingers feel greasy, it’s likely weighing down your hair,” she explains.
