Hair volume is how hair you have on scalp. It is typically thought of as how much lift there is at the root, how full hair appears and how thick it feels. Natural volume is determined by how many hair follicles grow per square inch of area on one's scalp and the thickness of those follicles.

To add volume to your hair, you can try a few techniques:

1 Blow-drying - Flip your head upside down while blow-drying to lift the roots and create volume.

2 Use volumizing products - Apply mousse, volumizing spray, or dry shampoo to add texture and lift.

3 Teasing or backcombing - Gently tease the roots of your hair to create volume. Remember to be gentle to avoid damage.

4 Haircut and layers - Ask your hairstylist for layers, as they can give the illusion of more volume.

5 Velcro rollers - Use velcro rollers while blow-drying to add lift and body to your hair.

6 Avoid heavy products - Heavy oils or conditioners can weigh down your hair, so opt for lighter products.

Experiment with these tips to find what works best for your hair type and desired look!
