what is the least amount of time i can leave it in at morning ?

HAIRMETTO Serum is non-oily and is designed as a 'leave in' treatment. There is no need to wash it out until you apply more since new application of the Serum should be applied to a cleansed scalp. If you wish to wash it out for some reason, the serum should be left on for a couple hours at least because the ingredients permeate the follicles, delivering the DHT blocking ingredients right where they are needed. If you would prefer to have an overnight treatment, you may like HAIRMETTO Oil - designed for overnight saturation, but because of its oily nature its usually not as desirable for daytime wear when going out.

How long will one bottle last on average? If it helps i keep my hair pretty short, at an inch or less

HAIRMETTO™ should be applied once a day and allowed at least 8 hours to fully absorb. As a general rule you would apply a similar amount as you would lotion on a given area of the skin. The amount of product used will vary from person to person as some people have very small areas of thinning and others larger. We have had reports of users with thicker hair having to apply more of the product to get an even distribution since the hair shaft itself absorbs some of what is applied to the scalp. It’s hard to answer for everyone because of various degrees of hair loss and different hair types. Some go through one bottle a month, others buy it every 2-3 months. If treating only the hairline 'cul-de-sac' areas, then one bottle may very well last longer than that. We hope this adds some clarification.

Can you use this and immediately put on normal hair gel to style?

Yes. HAIRMETTO® Topical Serum is a scalp treatment; your gel is a styling product for the hair itself. When using the Serum, massage it into the scalp. The remainder of the product on your hands will reach the hair strands, benefiting the hair itself. When you apply your gel styling product, try to avoid covering the scalp since most products will clog the skins pores on the scalp and interfere with the absorption of the nutrients in the topical scalp treatment. Styling products are for the hair itself.

How can i make sure i get the right version (stinging nettle) when i purchase? i've purchased twice now and had to return due to getting the wrong one

Hello, I just saw this question now so would like to still answer it. There was an issue with the barcodes being stickered wrong for a few weeks in the summer 2019. The issue was rectified by September and all product that was shipped incorrectly was replaced at no expense to the customer. We do apologize for the inconvenience this caused some customers and are happy to hear Amazon sorted it out so thoroughly.
