I am not sure if it would be bad to use on your hair after it has expired, but I will never use rancid oils on any part of my body. It's a personal preference.
I was cleaning my pantry this morning and I found a bottle of Flax seed oil that is quite a way past its use by date (the shame... I know I should clean more!) I was wondering would it still be OK to use as a treatment on my hair?

Id use it externally I think the expiry date is more a reference to taking it internally but I am not 100% sure?

Flaxseed and oil do have safety issues.
Flaxseed and oil
2008
".... few studies of flaxseed safety in humans. Flaxseed and flaxseed oil supplements do appear to be well tolerated in the available research, and there is long-standing historical use of flaxseed products without many reports of side effects.
.... unripe flaxseed pods are believed to be poisonous and should not be eaten. Raw flaxseed or flaxseed plant may increase blood levels of cyanide, a toxic chemical (this effect has not been reported when flaxseed supplements are taken at recommended doses). Do not apply flaxseed or flaxseed oil to open wounds or broken skin.
Pregnancy and Breastfeeding .... use of flaxseed or flaxseed oil during pregnancy and breastfeeding is not recommended. Animal studies show possible harmful effects, and there is little information in humans. Flaxseed may stimulate menstruation or have other hormonal effects and could be harmful to pregnancy."

"Pregnancy/Lactation
Documented adverse effects. Emmenagogue effects. Avoid use.
Toxicology
Theoretically, ingestion of large amounts may be harmful because of the cyanogenic glycosides."

"Warnings
.... case of anaphylaxis in a 39-year-old woman due to ingestion of flax has been reported ....
.... flaxseed has phytoestrogenic effects, patients with estrogen receptor positive (ER+) type of breast cancer should use flaxseed with caution.
Adverse Reactions
.... workers regularly exposed to flax at their job show immunologically positive antigen tests ...."

Flaxseed shouldn't be stored in your pantry. It goes rancid quickly and will keep better in the fridge.
I would just throw it out, rancid oil smells nasty.
Don't eat it.
It is probably safe for external use. Just give it the sniff test. Rancid oil is easy to discern. It's a pretty obnoxious smell. If it smells however flaxseed oil usually smells, use it in your hair without fear.
I have that same bottle in my pantry...how strange. I think I'll give it the sniff test and give it a try on my hair. I hate wasting things if I don't have to.

The oil STINKS! It's gone in the bin... if I used it on my hair I would never get the smell out.
I have taken note the next bottle I get will be kept in the fridge and used well with in the date!
