Red Rose said:Hi, just skimmed through this thread so may have missed a few points but I not convinced from what I have read that *on paper* xandrox is any more beneficial than bog standard rogaine.
1) there is no in vivo evidence for azelaic acid;
2) azelaic acid does not reduce sebum production (*);
3) 3ml of minoxidil is equivalent to 1ml of Xandrox 15%
Conclusion: Xandrox 15% is superior in terms of cost and economy, but that is all.
Any thoughts?

"Clinical and laboratory studies on treatment with 20% azelaic acid cream for acne"
Cunliffe WJ, Holland KT.
Department of Dermatology, Leeds General Infirmary, Yorkshire, England.
In a series of investigations using 20% azelaic acid cream as a therapy for acne, it was found that the treatment, compared with its placebo, significantly reduced inflamed lesions after 1 month and non-inflamed lesions after 2 months. No changes in sebum excretion rate occurred, but a significant reduction, 15.9 to 10.5%, of free fatty acids of skin surface lipid was detected after 1 month. The follicular Micrococaceae density was significantly reduced after 1 month, and after 2 months there was a significant reduction in follicular Propionibacterium spp density. The final reductions were 2,500 and 44 fold, respectively.

I think he even admits that. However, it's a lot easier to apply 1 ml than 3 ml. I think that's the only reason to use Xandrox 15.Red Rose said:yuppy75 said:there is a threshold level at which atrophied hair follicles will respond to minoxidil to produce a terminal hair shaft again.

There is no proof that 1ml of 15% minoxidil will grow more hair than
3ml of 5% minoxidil. The other points he makes relate to economics.
