Okay so I never make homemade beauty products. I confess, I fear I will make a mess and waste supplies.
But in searching for homemade gifts for guys I came across tons of recipes for aftershave. I amalgamated a few and took my chances...here they are....

I put them in flasks and put tags with various names such as Spiked! and Spiced and spiked.
This is so easy but you should start today if you want these to be gifts for Christmas.
You need 1/2 cup of vodka
spices mix for scenting
1/2 cup mineral water non carbonated
Small glass jar with lid
This makes one cup of aftershave.

In a clean jar place vodka and spices. Store in a cool place..I used the fridge. Steep for one week or longer. Shake gently sealed jars each day.

When you are ready strain the scented vodka. I used a coffee filter to make sure I removed all bits. Then I added the mineral water.
Funnel(..I had no funnel so I twisted a piece of paper into a cone) the aftershave into non porous containers of metal or glass. This should last up to 3 months. I recommend keeping it in the fridge it adds a cool sensation when using and lasts longer.
Because of the alcohol this acts also as a toner and antibacterial for nicks and cuts. The light scent lasts only an hour or so making it perfect for cologne wearers.
Here are some spice mix ideas.
#1 -- 2 bay leaves
15 whole cloves
1/2 tsp white peppercorns
#2-- star anise 1 or 2
1 cinnamon stick broken in half
10 cardamon seeds
2inch piece of vanilla
#3-- 1tsp cassia buds
1 star anise
1/4 tsp white peppercorns
2inch piece of vanilla bean
2 bay leaves
Try out whatever you like in the way of spices and then let me know. This is also great for a cheap Valentines or Fathers Day gift!
