I'm 37 and having been shaving my head since I was 19. I noticed my hairline was already receding, and both of my grandfathers were completely bald. It was only a matter of time.
So, I asked myself if I was going to be an insecure bitch about it and style my hair to try to hide it, wear hats, buy special shampoos, or get surgery... or go 'ahead' and shave it all off.
So, I've been shaving my head for 18 years now and have been loving it.
I shave once every two days at the latest using coconut lotion (never shaving cream) and Shavemob 4-bladed razors.
Handle + 24 Razors = $30
And these are the absolute best razors I've ever used. Expensive razors like Gillette seemed to maybe, at most get me through shaving my head and face twice before becoming completely dull. But with Shavemob blades, I can shave my head and face five or six times over.
Also, I always shave in the shower, it only takes 5 minutes, and using the spray to clean the blades every few strokes. This helps every razor last longer. The 6-bladed razors are great as well, but the blades are so close together it makes cleaning the hair out between the blades a pain, so that's why I recommend 4-blade razors.
With only shaving once every two days and using a razor for five or six shaves, that 24 pack of razors for $30 is almost a year's supply. Good luck finding a cheaper and better method for head shaving.
