I use Aegon Oil & it worked for me as I got this static hair that drove me crazy.
It started after I came off HRT, my hair was one of the first problems I encountered.
My hairdresser recommended it so I looked in Sains''' & a small bottle cost £4 but it has lasted for about 6 months & I'm only 1/2 way through it, you only need very little of it & it gives my hair a lovely shine.
