It is one of the most searched haircare questions for a reason.
Some people are told to wash daily. Others are encouraged to ‘train’ their hair to last a week. The truth, as with most things in professional haircare, is more complex. How often you should wash your hair depends on your hair type, scalp activity, lifestyle, environment and the products you use. There is no universal rule. There is only what supports your healthiest hair routine.
As a luxury haircare brand rooted in salon expertise, we believe in education over trends. So let us break this down properly.
If you are unsure about your hair type, take our Hair Quiz to discover where you sit on the 1A to 4C spectrum.
Why Do We Wash Our Hair?
Washing removes:
- Sebum produced by your scalp.
- Sweat from exercise.
- Pollution and environmental debris.
- Product build-up from styling creams, sprays or dry shampoo.
- Dead skin cells.
Your scalp is living skin. Just like facial skincare, it requires balance. Overwashing can disrupt the scalp barrier. Under washing can lead to congestion, irritation and dullness.
The key is understanding how your hair type behaves.
How Often Should Each Hair Type Wash?
Type 1: Straight Hair (1A, 1B, 1C)
Straight hair allows sebum to travel easily down the hair shaft. This often makes it appear oilier more quickly.
General guidance: 1-3 days
- 1A (very fine, very straight) may need washing every 1-2 days.
- 1B can often stretch to 2-3 days.
- 1C, which is slightly thicker, may manage 3 days comfortably.
Fine straight hair is particularly prone to limpness from products build-up. A gentle but effective cleanse is essential.

Type 2: Wavy Hair (2A, 2B, 2C)
Wavy hair sits between straight and curly. Sebum travels less easily meaning it can go slightly longer between washes.
General guidance: every 2-4 days
- 2A often behaves similarly to straight hair.
- 2B may comfortably wash every 3 days.
- 2C, with stronger wave patterns, may stretch to 4 days.
Wavy hair benefits from maintaining natural oils to support definition. Overwashing can increase frizz.
Using a sulphate-free formula from a trusted UK haircare brand like Moo & Yoo helps preserve natural moisture while delivering salon quality haircare at home.

Type 3: Curly Hair (3A,3B,3C)
Curly hair struggles more with oil distribution because of its spiral structure. This often results in drier mid-lengths and ends.
General guidance: every 3-7 days
- 3A curls may wash every 3-4 days
- 3B every 4-6 days
- 3C may wash weekly
Hydration is critical. Washing too frequently can cause dryness and breakage.
In between washes, refreshing curls with water or a light leave-in can maintain shape without full cleansing. Our sustainable haircare approach focuses on gentle cleansing that respects curl integrity and sensitive scalps.

Type 4: Coily Hair (4A,4B,4C)
Coily hair has the tightest curl pattern. Sebum has the most difficulty travelling down the shaft.
General guidance 7-14 days
- 4A may wash weekly
- 4B and 4C often every 10-14 days
Moisture retention is the priority. Cleansing should be thorough but gentle.
Low manipulation routines and rich conditioning are key to maintaining strength. Luxury haircare for coily hair should feel nourishing, never stripping.

Other Factors That Change How Often You Should Wash
Hair type is just one part of the picture.
1. Exercise
If you exercise daily and sweat heavily, you may need to cleanse more often. However, not every workout requires a full shampoo. Rinsing or co-washing can help maintain balance.
2. Product Build-Up
Frequent use of styling creams, oils, dry shampoo or hairspray increases the need for cleansing. Build-up can block follicles and flatten volume.
Signs of build-up include:
- Hair feeling coated or heavy
- Dullness
- Itchy scalp
- Styles not holding properly
3. Environment
Urban pollution, hard water, and humid climates all impact how quickly hair feels unclean. Environmental stressors can justify more frequent washing.
4. Scalp Health
If you experience sensitivity, flaking or irritation, over washing may be the issue. Equally, infrequent washing can worsen congestion. A balanced, natural haircare routine supports scalp integrity.
How To Find Your Personal Washing Rhythm
1. Identify your hair type using our Hair Quiz.
2. Start with the recommended frequency above.
3. Observe how your scalp feels after 48 hours.
4. Adjust gradually. Add or remove one wash per week as needed.
5. Choose high-quality, sustainable haircare formulated for your needs.
There is no prize for washing less. There is no virtue in washing more. There is only balance.
Healthy hair is not about restriction. It is about listening.
So, how often should you really wash your hair?
As often as your scalp requires to remain balanced, comfortable and clean.
