Please can somebody tell me which is a person more likely get more regrowth with multi galvanic or blend?
With good practitioner skill, neither. One gets good at galvanic faster, than one gets good at blend, so it is more possible to have an ineffective blend treatment, than an ineffective galvanic only treatment. One will get more hairs per hour in blend, than galvanic, however, so one should consider that although some may say that galvanic is best because one is most assured of the efficacy of each hair treated, in the end, one wants good work on the most hairs that can be possibly treated in the time you have the work done. That is why competent work with a thermolysis provider is most sought after, as the number of hairs per hour is the higest, and when the practitioner skills are high, so is the efficacy. This results in little to no regrowth.
Now since you are asking about “regrowth” you must understand what regrowth is not, as well as what regrowth is. It takes A WHOLE YEAR to see regrowth, as one could not tell that there was any until one compares a before picture taken just before treatment, with an after picture taken after the treatment was done, and then one more picture taken the same day a year later.
Regrowth is not what you see 3 to 6 weeks later, as that is just different hairs coming in on schedule. You need 9 months minimum for all hairs to show themselves at least once.
