How Often Should You Wash Your Hair: The Complete Guide

How Often Should You Wash Your Hair: The Complete Guide

How often should you wash your hair? This question has been asked for as long as people have used hair shampoo. The answer, however, is more complex. Depending on your hair type, scalp condition, scalp oil level, and lifestyle, the answer could be anywhere from washing your hair daily to once a week. This comprehensive guide will break down everything you need to know about how often to wash your oily hair, thick hair, and every other hair type. Let's take an in-depth look at the factors contributing to deciding how often you should wash your hair.

Hair Type

This applies to not only the different types of hairstyles but also the different types of hair. Just like our skin and nails, our hair has different types and not just the difference between fine and thick hair. The type of natural hair we have will tell us how often we should wash it.

Normal Hair

You're in luck if you have what is considered 'normal' hair. You can wash this type of hair every day without any problems. In fact, washing your hair every day is a good thing. It will help to keep your hair clean and free of any dirt or build-up that can happen throughout the day.

Dry Hair

If you have dry hair, you'll want to wash it every other day. Washing your hair daily can strip it of its natural scalp oil and make it even more dehydrated. But if you go too long without washing, your hair will look greasy and heavy. Every other day is a good balance for dry hair.

Oily Hair

Oily hair is the opposite of dry hair. You'll want to wash your hair daily if you have oily hair. Not washing your hair will only worsen the oil build-up and give you greasy, stringy hair. But be careful not to overdo it – washing your hair too much can strip it of its natural scalp oil, leading to dryness.

Damaged Hair

Damaged hair is fragile, and you need to treat it with care, so you'll want to wash it every other day or every third day. Washing your hair daily will only make the damage worse. But if you go too long without washing, your hair will look greasy and heavy. Every other day or every third day is a good balance for damaged hair.

Treated Hair

You'll want to be extra careful if you have treated hair, such as color treated or chemically treated hair. Treated hair is more fragile, so treat it with care. Like damaged hair, washing your hair daily can strip it of its natural oils and make the damage worse. You'll want to wash your treated hair every other day or every third day.

In addition, how often you should wash your hair depends on the type of hair you have. For example, people with straight hair can go longer without washing because the natural oils tend to distribute evenly. On the other hand, people with curly or coiled hair should wash more often because the natural oils don't spread as evenly and can lead to build-up. Those with thick hair can also go longer without washing because it doesn't get as greasy. Finally, wash fine hair more often because it gets greasy faster.

Scalp Condition

Understanding your scalp's condition is essential in deciding how often you should wash your hair, as it is the scalp that produces the oil.

You can wash your hair more frequently if you have a dry scalp. A good rule of thumb is to wash your hair every other day or every three days if you have a very dry scalp. If you have an oily scalp, you should wash your hair every three or four days. If you have a sensitive scalp, finding a balance that works for you is vital. You may need to experiment to find the proper washing schedule and products for your scalp.


In the old days, there were few choices regarding how often you should wash your hair. When you were part of a large family, you used the same comb, and if you were lucky, you got to use the same soap. In addition, you may find your 'allocated bath time' may only fall once a week, so only a little attention was given to hair care routines!

Like most people, you probably grew up washing your hair every day. However, that may be optional, depending on your lifestyle. If you have an active lifestyle, you may need to wash your hair more often than someone with a sedentary lifestyle.

A stay-at-home mom, for instance, might not need to wash their hair every day. If you don't get out much and don't sweat, your hair may not get as dirty as someone who works outside or exercises regularly. On the other hand, if you have a job that requires you to be in contact with people all day, you should wash your hair more often.

It's essential to find a balance between all these factors – your scalp condition, hair type, and lifestyle – to figure out how often you should wash your hair.

How Long Can You Leave Between Washes?

It depends on your hair type, how often you work out, and whether you have oily hair. If you have oily hair or sweat a lot, you might need to wash your hair every day or every other day. If you have dry hair and don't sweat much, you can get away with washing your hair every few days. However, if you have really dry hair, you might only need to wash it once a week! So, it varies.

But if you're like most people, you fall somewhere in the middle and need to wash your hair every two or three days. Of course, you can still wet your hair in between washes! Wetting your hair will help remove any build-up and will also make your hair look fresher. Just be sure to use a gentle, sulfate-free shampoo if you decide to wash your hair more than once a week.

If you want to extend the time between washes, you'll need to do it gradually. Your scalp has its own built-in oil thermometer, and to begin with, it will continue to produce oil at the same rate, so you may have to put up with an oily scalp for a little while. Just be patient – it will adjust!

Start by washing your hair every other day and then every third day and see how your scalp responds. If it starts to get too oily, you can always go back to washing it more frequently. And if your hair is beginning to look dull, try using a dry shampoo in between washes to help absorb any excess oil.

Does Overwashing Damage Your Hair?

Washing your hair too often can strip it of its natural oils, leading to dryness, frizziness, and breakage. It can also cause scalp irritation. If you're washing your hair daily or even every other day, try cutting back to once or twice a week.

Use a gentle shampoo and condition your hair to help replace lost moisture. It's also essential to use products tailored to your hair type. If you have oily hair, look for shampoos specifically designed to control oil production. And if you have color-treated hair, use a shampoo and conditioner that are formulated to protect your hair color. Washing your hair less often will help keep it healthy and looking its best.

How Does Shampoo Work?

Shampoo is designed to clean your hair and scalp, but it can also do much more than that. Some shampoos are specifically formulated to treat dandruff, dryness, and other scalp conditions. In addition, some shampoos can create thicker hair, control scalp oil, add shine, and other benefits to your hair.

When you apply shampoo to your hair, the surfactants in the shampoo attach themselves to the scalp oil and dirt. The surfactants can lift these oils and dirt away from your skin and hair, taking them with them when you rinse the shampoo out. Ensure you rinse thoroughly to remove all traces of shampoo, especially in thicker hair.

Choosing the Right Shampoo

Your hair is your crowning glory, so you want to make sure you choose the right shampoo to keep it looking its best. But with all the different types and brands on the market, how do you know which is right for you?

Here are a few things to consider when choosing a shampoo:

Hair type: Whether you have oily, dry, or normal hair will help determine which shampoo is right for you.

Scalp: If you have a sensitive scalp, you'll want to avoid shampoos with harsh chemicals.

Budget: You don't have to spend much money on good shampoo. Plenty of affordable options will work; however, as with many things, you get what you pay for.

Your hair goals: Are you looking for a shampoo that will add volume, creating thicker hair? Or one that will help control frizz?

Knowing what you want your shampoo to do will help you narrow your choices.

How Does Conditioner Work?

Conditioner works by coating the hair shaft and filling in any damaged areas. This creates a barrier that protects the hair from further damage and makes it appear shiny and healthy. Conditioner also helps to detangle the hair, making it easier to style. Conditioner is a must for thick hair if you want to be able to manage it!

All conditioners contain some oil, which coats the natural hair and provides the conditioning effect. The type of oil used will vary depending on the conditioner, but common oils include:

olive oil

coconut oil

argan oil

In addition to the oil, conditioners contain ingredients that help improve the hair's texture and appearance. These ingredients can include proteins, which help to repair the damage, and silicones, which smooth the hair and prevent frizz.

Conditioners are available in a variety of formulas, including:

Deep conditioners: these are designed to penetrate the hair shaft and repair damage

Leave-in conditioners: lighter formulations that can be left in the hair to provide ongoing conditioning

Rinse-out conditioners: these are the most common type of conditioner and are meant to be rinsed out after use

Choosing the right conditioner depends on your hair type and needs. For example, dry or damaged hair may benefit from a deep conditioner. In contrast, those with oily hair may prefer a lighter leave-in conditioner. No matter what type of conditioner you choose, apply it evenly from root to tip and rinse it out thoroughly, which is especially important for thick hair.
