Introduction

Just as skincare begins with understanding your skin type, effective hair care hinges on identifying your hair type. Your hair type is defined by multiple parameters including sebum (oil) secretion, strand shape (curl pattern), and hair shaft texture. A clear understanding of your hair’s biology allows you to choose the right shampoo, conditioner, styling products, and hair care practices — leading to healthier, more manageable hair.

This guide classifies hair types based on three key factors:

1. Scalp oil secretion
2. Curl pattern
3. Hair shaft texture

Hair Type Based on Oil Secretion

1. Oily Hair

Characteristics:

• Hair feels greasy and limp even a day after washing.
• Scalp appears shiny due to excess sebum.
• Prone to scalp acne, dandruff, and clogged follicles.

How to Identify:

• Blot the scalp with a tissue within 24 hours of shampooing. If oil is visible, you likely have oily hair.
• Observe how long your hair stays fresh after washing.

Care Tips:

• Use mild, sulfate-free shampoos formulated for oily scalp.
• Shampoo daily or every alternate day.
• Avoid heavy conditioners on the scalp — use only on the mid-lengths and ends.
• Incorporate a clay or charcoal scalp mask weekly to detox excess oil.

2. Dry Hair

Characteristics:

• Feels rough, dull, and brittle.
• Tends to break easily and split at the ends.
• Scalp may feel tight or flaky.

How to Identify:

• Hair appears frizzy and lacks shine even after conditioning.
• Breaks easily when combing.
• Scalp shows flaking not caused by oiliness (dry dandruff).

Care Tips:

• Use deeply hydrating shampoos with ceramides, glycerin, or hyaluronic acid.
• Apply rich conditioners and weekly hair masks.
• Limit shampooing to 2–3 times a week.
• Avoid heat styling and always use a heat protectant spray.

3. Normal Hair

Characteristics:

• Balanced oil levels.
• Shiny, soft, and manageable.
• Minimal frizz or breakage.

How to Identify:

• Hair looks healthy for several days after washing.
• Minimal dandruff or scalp issues.

Care Tips:

• Use a gentle, pH-balanced shampoo.
• Deep condition once a week to maintain health.
• Trim every 6–8 weeks to prevent split ends.
• Maintain a balanced diet to support hair growth.

4. Frizzy Hair

Characteristics:

• Hair appears unruly and puffy, especially in humid conditions.
• Feels dry to touch even after washing.
• Difficult to style or maintain smoothness.

How to Identify:

• High porosity strands that absorb moisture quickly and become frizzy.
• Hair swells in humidity or after drying naturally.

Care Tips:

• Use silicone-free anti-frizz serums and leave-in conditioners.
• Incorporate proteins like keratin and amino acids.
• Avoid brushing dry hair — use a wide-tooth comb when wet.
• Sleep on a silk pillowcase to reduce friction.

5. Combination Hair

Characteristics:

• Oily scalp with dry or frizzy ends.
• Common in long hair or in individuals using harsh shampoos.

How to Identify:

• Scalp feels greasy within a day or two post-wash, but ends remain dry or damaged.
• Tangles and split ends with oily roots.

Care Tips:

• Use a clarifying shampoo at the scalp and a nourishing conditioner on the ends.
• Consider double cleansing: gentle shampoo for scalp, moisturizing shampoo for lengths.
• Regular haircuts to manage split ends.
• Scalp exfoliation once a week to control oil buildup.

How to Identify Your Hair Type Based on Oil Secretion?

The Tissue Test:

• Perform this test on the second day after shampooing.
• Gently press a blotting tissue or clean paper towel onto the scalp.
  • Oil blot present: Normal hair
  • No oil and scalp feels tight: Dry hair
  • Hair strands clump together and feel greasy: Oily hair

Hair Type Based on Curl or Wave Pattern

The degree of curl in your hair is genetically determined and affects how your hair behaves in terms of volume, moisture retention, and styling needs.

Care Notes:

• Curlier hair tends to be drier due to difficulty in sebum travel along the hair shaft.
• Use curl-defining creams or gels and avoid brushing dry curls.

Hair Type Based on Thickness and Texture

This classification refers to the diameter and strength of individual hair strands and is often used alongside the curl pattern classification.

Care Notes:

• Type A: Prone to oiliness, needs volume-boosting products.
• Type B: Balanced; benefits from lightweight moisturizers.
• Type C: Needs deep hydration and detangling products.

Comprehensive Hair Care Tips for All Hair Types

• Avoid daily heat styling; always use a heat protectant.
• Protect hair from UV rays with hats or hair sunscreens.
• Use silk pillowcases to reduce hair breakage and frizz.
• Maintain a balanced diet rich in protein, biotin, and omega-3s.
• Trim regularly to prevent split ends.
