Understanding Different Types of Hair and Their Needs

Advice that works beautifully for one person can leave another person’s hair limp or frizzy. That is usually because their hair types differ. Understanding your own combination of curl pattern, strand thickness and scalp oiliness makes it far easier to choose products and habits that suit you.

The features that define hair type

Shape or curl pattern

Hair is often described as straight, wavy, curly or coiled. The shape is determined by the hair follicle and is largely inherited.

Strand thickness

Individual strands can be fine, medium or coarse. Fine strands are easily weighed down; coarse strands can feel rougher and usually tolerate richer products.

Density

Density is how many hairs grow on your scalp. You can have fine strands but a lot of them, or coarse strands that are sparse.

Scalp oiliness

The scalp produces an oil called sebum. Some scalps produce a lot, some very little, and this changes with age and hormones.

What each type tends to need

Straight hair

Sebum travels easily along straight strands, so straight hair often looks oily sooner. Frequent washing with a mild shampoo and a light conditioner on the ends usually works well.

Wavy hair

Wavy hair sits in between: it can be oily at the roots and dry at the ends. Lightweight conditioning and avoiding heavy products near the scalp help keep waves defined.

Curly hair

Curls make it harder for oil to reach the ends, so curly hair is commonly drier and more prone to frizz. Less frequent washing, generous conditioning and gentle detangling are typical needs.

Coiled or tightly textured hair

Tightly coiled hair is the most fragile where it bends and tends to be the driest. Dermatologists often recommend washing once a week or every other week, using conditioner with every wash, and handling the hair gently to prevent breakage.

Fine versus coarse strands

• Fine hair: choose light formulas and apply conditioner only to the ends.
• Coarse or thick hair: richer conditioners and an occasional mask, such as Repair Hair Mask, help with softness.

Your hair type can change

Hormonal shifts, aging, medicines, coloring and heat styling can all change how hair behaves. Hair that has been chemically treated usually needs more moisture than it did before, whatever its natural type.

A quick way to assess your hair

Wash your hair, skip styling products and let it air-dry. Note the shape it takes, how soon the roots look oily over the next days, and whether the ends feel dry. Those three observations tell you most of what you need.

The bottom line

Knowing your curl pattern, strand thickness and scalp type turns product choice from guesswork into a short checklist. You can filter our hair care range by product type once you know what your hair needs.
