Personally, I have extended the time between washes for my hair. My hair used to be distinctly, noticeably drier and frizzier with many split ends, when I washed it frequently. When I saw my hairdresser recently, which I'd been able to do, due to an incurable chronic illness, chemotherapy,
and various other powerful drugs. He was amazed as I had no split ends and in really excellent condition.
I know my hair doesn't smell; my husband doesn't hold back with any criticism. I don't smoke and I don't have pets, either. I spend very little on clothing. I tend to wear things until they wear out. If the clothing is repairable, that's what I do.
Personally, I wonder if we wash our hair too often, as a population?! I wash my hair with
only one squirt from my shampoo & conditioner. I really make sure my hair is well and truly lathered, all over and leave the conditioner in for as long as possible.
When I worked in a school I used to get really paranoid and check my hair with a nit comb. I never had nits; 🐜it was due to an allergy to whichever bargain shampoo/conditioner I was using at that particular point🙄.
Now that I've found one, that doesn't drive me totally bonkers; scratching my head like a demented lunatic! It's the only one I'll now use. It isn't cheap; £100 for a litre of both, but they last very close to 18 months. This is my only vice; I don't smoke, drink, rarely go out with friends, absolutely nothing. The shampoo and conditioner are in one litre bottles and I use one pump from each, per wash. A very goes a very long way.
I'd probably spend close to that if I used a cheaper shampoo, but I'd have the constant irritation, too. I have had anaphylactic shock in the past too, so I don't want to risk yet another.
Personally, I prefer to put my comfort first before making my scalp so irritated that I look like a demented lunatic scratching my head every couple of minutes.
I know that years ago on television there was a woman who was challenged to not wash her hair for a month. she came back a month later and her hair looked amazing. It was only years later that she admitted that it got so skanky and gross, that she washed it midway through the experiment!
But to never wash your hair? Uuugghhh, gross! Doesn't bear thinking about... 😝
Life's too short.
