How to Wash Your Hair Once a Week | Pros and Cons

I get a lot of questions when I tell people I only wash my hair once a week. Is that even healthy? What products do you use? Doesn’t it feel dirty? The answers to those questions will vary from person to person, but for me, washing my hair once a week works. I know there are a lot of women out there wondering how they can cut back on how often they’re washing their hair, and I want to be able to give you all some answers straight from a professional. So when I went to get my hair done a couple of weeks ago, I asked my hairdresser about hair health, how often we should be washing our hair, and if you can actually train your hair to require less washing. Today, let’s dive in to how to wash your hair once a week, along with some pros and cons of cutting back on your shampoo routine.


I haven’t always washed my hair just once a week. When I was a teenager, I washed my hair almost every day, and getting to the point where I could wash my hair once a week didn’t happen overnight. It was a progression, and it will be for you, too, if you’re accustomed to washing your hair multiple times during the week. However, I now have a routine in place and products in my rolodex that really work for me and my schedule.

5 tips on how to wash your hair once a week:

1. Use a different shampoo and conditioner each time you run out. This helps me keep my hair shiny and hydrated. When you shampoo your hair once a week, you want to make sure when you do wash it, it’s getting all of the nutrients it needs to stay healthy. Using the same product over and over means your hair is getting the same vitamins and minerals over and over. You may be surprised about how healthy your hair feels after switching up shampoo and conditioner.

2. Use volumizing spray. It doesn’t matter how dry or oily your hair naturally is, if you haven’t washed it in several days, it is going to have more oil and product in it than it did at the start of the week. I like to use a volumizer/texturizer to give my locks a lift when they’re starting to fall flat, and Kerastase VIP spray is my favorite product right now. Apply it at the root and gently work it through your hair with your fingers for extra body (you’ll notice the difference right away).

3. Brush your hair two to three times a day. This will help with oil distribution. When you’re trying to cut back on how often you’re washing your hair, eliminating and managing oil on your scalp is going to be important. I brush mine in the morning, in the afternoon after I hit the gym, and when I get home from work. I also always apply a little bit of dry shampoo before I brush my hair throughout the day to help with controlling the oil on my scalp.

Don’t let this tip sound sound like more work than it is. You’re not always going to have to brush your hair this often throughout the day. How frequently I brush my hair/apply dry shampoo is often determined by whether or not I’ve worked out that day and weather conditions. Use your best judgement!

4. Find a good dry shampoo. My number one tip on how to wash your hair once a week? Find a dry shampoo you like and carry it with you at all times. My dry shampoo has a permanent place in my purse. I take it to work, to the gym, and to run errands. I try to use a little bit at a time throughout the day instead of laying it on thick first thing in the morning. Amika Perk Up Dry Shampoo is my product of choice. I love that it has a clear finish, so you don’t have to worry about white residue. It’s also not sticky or oily!

5. Keep your hands out of your hair. If you’re always running your fingers through your hair, you’re going to have trouble with keeping it clean longer. The oil on your fingers can and will transfer to your hair when you touch it. If you feel like you need to touch your hair to work out a tangle or get it out of your face, try to use a comb or brush instead of your hands.

Can you train your hair so that it only needs to be washed once a week?

One question I get asked a lot is whether or not you can train your hair so that it doesn’t need to be shampooed so frequently. I took this question to my hairdresser, and she had good news. Yes, you can train your hair so that you don’t have to wash it every day. She essentially said when you wash your hair, you’re ridding it of all of the oil and product that’s accumulated since the last time you washed it. When you’re washing your hair every day, it gets used to producing oil every day. When you cut back on how often you’re washing your hair, your locks will learn to not produce so much oil.

So if you are someone who washes their hair every day, the good news is you CAN get out of that routine. Start by skipping your hair-washing routine twice a week. Get comfortable with your hair looking oily at the end of the day, and don’t forget to pack your dry shampoo and hairbrush in your bag. If you notice you’re hair is starting to look a little bit too shiny/flat during the day, use a little bit of your dry shampoo/volumizer and give your locks a good brush.
