Getting married! Need quick hair thickening advice

[Slab]

Hi all

Over the past 5-6 years I have been very slowly losing my hair, my hairline isn't too bad but its receding alot more than it used to. My biggest concern is how thin its getting ontop, sometimes when the light hits it you can see a bit of scalp!

I have been using 5% minoxidil for a couple years now, and I go through phases where my hair looks very full, then other times (like now) it feels really brittle and thin.

I get married in less than 2 months, so am hoping between now and then it'll improve, but just in case are there any products out there that can thicken my hair up? Its only for the one day really, I've tried thickenig shampoos but they dont make any difference IMO.

Thanks
