Yes, there is no harm in washing hair daily with plain treated water but prefer cold water. You need to check for excess chlorine or bleach in water which may cause dryness and split ends on repeated exposure.
You can also use only water to wash your hair. This method works best for people with curly, thick, coily and coarse hair. Also, if you have tangle-prone hair, you can choose to clean your hair only with water and then go for a deep conditioner.
Shampoo and Greasy Hair
Once you stop using shampoo on a regular basis, as the theory goes, oil production slows down and you naturally produce less. (You may experience a few greasy days or weeks of "transition period," proponents say, but eventually, your body finds balance again.)
With the no-poo method, your hair is still being cleansed, just not with shampoo, therefore eliminating the risk of stripping away those natural oils. Ultimately, it ensures that the hair and scalp are balanced and healthier.
Many beauty experts say that it's okay to skip your hair washing after a workout. Rinsing with water may be enough. In addition to saving time, skipping your post-workout hair washing every once in a while can actually be beneficial for your scalp health.
Yes, you can wet natural hair everyday, and it is actually advised to do so to maintain moisture.
"With more natural oils lubricating the hair [from water-only washing], the hair shafts glide over each other, leading to less tangles." Skipping shampoo also allows for the hair's sebum to distribute throughout, and this may make hair appear more shiny and less frizzy.
Instead of using shampoo on the daily after you've got all sweaty, simply use the water-only method and then use an alternative shampoo once or twice a week. Your hair will be relieved after being used to all that washing with conventional shampoo.
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.
Despite the rave reviews of some vloggers, most hair professionals do not recommend the water only hair washing method. “Sebum is naturally quite waxy (and smelly), and water alone may not be able to remove the buildup which can be problematic for people with scalp conditions or a predisposition to scalp conditions.
For most people, shampooing the hair is not necessary for good health. Just rinsing the hair with water a few times a week will remove most visible dirt and debris. The decision about how frequently to wash the hair is a cosmetic one based on personal preference.
Depending on how dirty your hair is, no washing may be as simple as tying your hair up in a towel or shower cap while you shower, keeping it dry during your shower. If it feels like it really needs a rinse, you might get it wet but not use any shampoo or conditioner.
Benefits of Skipping a Wash
Washing your hair daily can strip your scalp of its natural microbiome and can cause dryness and inflammation. Over washing can also leave your hair brittle, limp and thin. If you have highlights or colored hair, less water exposure will ensure the color lasts longer.
If you wash your hair too often, you can trigger an overproduction of those natural oils, creating excess sebum production, and bang—you've got greasy hair the next day, or even just hours after rinsing.
Make it Gradual
This may take about a week or so, depending on how heavy your shampoo and conditioner are. Every time that your scalp feels adjusted add another day in between washes! By the end of the month, you may already be a once-a-week washer!
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.
