shampoo can strip your hair of natural oils, and using heat products on your hair over and over again causes further damage and breakage, so washing your hair only once a week actually helps keep it in great condition.
Prolonged periods of not washing can cause cause buildup on the scalp, damaging hair and even impeding its ability to grow, Lamb said. Grime from dirt, oil and hair product can show up within four to six days for people with finer, straighter hair.
Coily hair: Both Courtney and King suggest washing once per week for optimal hair growth. "Don't forget to follow with conditioner," King adds. "It's equally as important to condition as much as it is to cleanse."
For the average person, every other day, or every 2 to 3 days, without washing is generally fine. “There is no blanket recommendation. If hair is visibly oily, scalp is itching, or there's flaking due to dirt,” those are signs it's time to shampoo, Goh says.
Hair Washing Frequency and Tips
“I recommend washing your hair two to three times a week,” Dr. Icecreamwala says. “If your hair is dry, you may only want to wash it twice a week. If it is on the oilier side, every other day is recommended.”
When to wash. Rossi generally tells his patients they should wash their hair once or twice per week. But if you've had chemical treatments that can make your hair drier — such as bleach, perms or relaxers — you might want to wash it less than once weekly to avoid breaking or brittle hair or split ends, he said.

Lifestyle and diet changes to fix oily hair
Your diet should consist of foods rich in vitamin B, especially B2 and B6. It is believed that these components in your diet can help keep your sebum production in control. So, consider adding foods like leafy vegetables, pulses, and seaweed.
Not Getting Enough B Vitamins
What you eat does affect every inch of your body, right down to the ends of your hair. According to HealWithFood, a person's B vitamin intake directly affects a person's level of sebum (oil) production.
Your hair at this age: Sebum (oil) secretion tends to diminish in our 60s and 70s+, and this can make the hair dry and brittle.
If a person has an oily scalp, then they may need to wash their hair as often as once a day. As a person ages, their scalp produces less oil, meaning they may need to wash it less often over time.
Overproduction of sebum leads to blockage, inflammation, and hardening in the pores. That, in turn, leads to the thinning of the hair with accompanying hair loss. So, oily scalp can cause the hair to fall out faster than it can grow back.
If you normally wash everyday, it'll take time to get used to washing it less. So start by going an extra day or two in between your normal washes. Rinse your hair with water in between shampoos and try to build up to once a week. When your hair adjusts you'll notice a dramatic difference.

A single hair has a normal life between 2 and 7 years. That hair then falls out and is replaced with a new hair. How much hair you have on your body and head is also determined by your genes. Nearly everyone has some hair loss with aging.

Is Oily Hair Healthy? Oily hair isn't healthy or unhealthy by default. People with an oily scalp can have healthy hair or dry, brittle hair. Your hair needs oil to be healthy, but too much oil can lead to buildup on the hair and scalp.
Modern lifestyles have led to an increase in anxiety and stress levels, making them one of the most common causes of oily hair. “Stress causes your cortisol levels to rise. Cortisol stresses out the oil glands to produce more sebum, naturally leading to oily hair,” explains Sethi.
