How long should 1.2 liters of head and shoulder shampoo last?

[Anonymous]

I bought it because I have a dandruff and I wonder how long does it last?

[NuitBlanche]

Liquid soap or shampoo is usually dosed too much, which is also the will of the manufacturer because they can sell more. If it foams like in advertising, it is already too much. For me, a bottle of shampoo lasts about 9 months. But I also know many who use hair soap. For the hands and the body I also take normal soap. Oh e perfume or other chemistry that can promote allergies

[NotInterestedSorry]

Mine has lasted for a few months. You don't have to use much when you wash your hair, and it's not recommended to wash your hair everyday, unless advised by a dermatologist

forever, cause i'd never use it. i'd just wash my hair less or only with water for a longer period of time. that usually makes your head skin recover and be less dry. yeah my hair will look greacy but it's worth it.

Unfortunately I have seb derm so I really have to use a shampoo that has anti dandruff ingredient

[genericname85]

i'd focus on curing that disease rather than fighting it's symptoms.

[Asker]

Lol It has no permanent cure only temporary cure. Unfortunately its lifelong disease :( and its auto immune

[genericname85]

xD temporary cure is an oxymoron.

[Asker]

Lol sorry Im not native English speaker 😆 Its just you have to use shampoo and oitment to somewhat control it. If I dont use shampoo my hair is like soak in a gel super oily

[genericname85]

super oily but still dandruff?

[Asker]

Yes thats one of symptom of seborrheic dermatitis. Its flaky dandruff. All over my hair.

Depends on how long your hair is and how often you shower.

[Asker]

I shower Once a day. 7 days a week.

Would last me a life time (I trim my hair very short, generally don't use shampoo)

[jennifer_bloom]

I would say 40 days.
