It's worth trying out some Body Shop Ginger Anti Dandruf shampoo (with Piroctone Olamine). It's only about £5. It performs slightly better in tests and I personally find it not nearly as harsh as Nizoral.
Here's the study from a legitimate source.
Nudging hair shedding by antidandruff shampoos. A comparison of 1% ketoconazole, 1% piroctone olamine and 1% zinc pyrithione formulations.

Hair shedding and hair thinning have been reported to be affected by dandruff and seborrhoeic dermatitis. The present study was conducted in 150 men presenting with telogen effluvium related to androgenic alopecia associated with dandruff. They were randomly allocated to three groups receiving each one of the three shampoos in the market containing either 1% ketoconazole (KTZ), 1% piroctone olamine (PTO) or 1% zinc pyrithione (ZPT). Shampoos had to be used 2-3 times a week for 6 months. Hair shedding during shampoo was evaluated semiquantitatively. Hair density on the vertex was evaluated on photographs using a Dermaphot. Trichograms were used for determining the anagen hair percentage and the mean proximal hair shaft diameter using computerized image analysis. The sebum excretion rate (SER, mug cm(-2) h(-1)) was also measured using a Sebumeter(®). The three treatments cleared pruritus and dandruff rapidly. At end point, hair density was unchanged, although hair shedding was decreased (KTZ: -17.3%, PTO: -16.5%, ZPT: -10.1%) and the anagen hair percentage was increased (KTZ: 4.9%, PTO: 7.9%, ZPT: 6.8%). The effect on the mean hair shaft diameter was contrasted between the three groups of volunteers (KTZ: 5.4%, PTO: 7.7%, ZPT: -2.2%). In conclusion, telogen effluvium was controlled by KTZ, PTO and ZPT shampoos at 1% concentration. In addition, KTZ and PTO increased the mean hair shaft thickness while discretely decreasing the sebum output at the skin surface.
Piroctone Olamine(PTO) outperformed Nizoral (KTZ) and Head and Shoulders((ZPT) in its ability to increase hair shaft diameter in AGA. Both Nizoral and PTO also reduced sebum emission, demonstrating an anti-androgenic effect.
The implication of this study is that P.O. shampoo, used 2-3 times weekly will likely provide even more of a benefit to treating hormonal hair loss than Nizoral shampoo. This is exciting news given Nizoral’s proven track record.
Thanks withnail

that's what results I was hoping for when I put this regime together
I was hoping for each shampoo to do the following jobs:
*T-gel therapeutic (coal tar) shampoo: clear dandruff and keep it at bay
*Nizoral: have the anti-androgenic effect, slow hair shedding, and increase hair shaft diameter, thus slowing down hairloss
*Alpecin double effect caffeine shampoo (contains Piroctone Olamine and caffeine): as Nizoral but with the added effect of caffeine to stimulate hair root growth (I am hoping it has a similar effect as minoxidil)
I mainly keep using the T-gel as I wash my hair daily and didn't want it to be blasted too much by the ketoconazole (Nixoral) and piroctone olamine (Alpecin).. Over the week I use T-gel x3, Nizoral x2, Alpecin x2.
If anyone has any ideas about changing this routine to maximise hair retention please let me know.
I want to have a regime that had both ketoconazole and piroctone olamine to give myself the maxiumum chance of retaining my hair without resorting to meds..
I may add the Body Shop Ginger Anti Dandruf shampoo (with Piroctone Olamine), or do people think that would be subjecting my scalp to too much PTO each week...? Any comments on the vurtues of caffeine in hairloss would also be welcome.
Cheers everyone and good luck
