Millions of men have used the best alum block brands for centuries to heal minor bleeding, nicks, and razor burn.

Besides using them on your face, some people use alum blocks for head shaving or as a deodorant.

Luckily for first-time users, it’s not that expensive to get your hands on great alum blocks nowadays. Below, we’ll tell you about five of the greatest alum blocks now on the market. The main criteria taken into account on this best alum block list include affordability, customer reviews, and durability. This best alum block list starts with the cheapest blocks and ends with the most expensive brands.

1. Gentleman Jon Alum Block

Price: $8.

The best alum block in terms of price is the Gentleman Jon Alum Block. It will only cost you $8 for a massive 3.7-ounce block. You’ll also get a sturdy plastic case with this purchase. All of Gentleman Jon’s alum blocks are made of potassium in China and distributed through their New York office. There are no additives to Gentleman Jon’s block, which means this product is totally fragrance-free.

The only major complaint customers have about this block is that it can crumble easily. But, considering the low price you’re paying, the Gentleman Jon Alum Block is a great way for you to test an alum block for the first time. As long as you dry off the block after every usage, this product should last you at least a year.

2. PAA Potassium Alum Block

Price: $7. 

Like Gentleman Jon, Phoenix Artisan Accouterments’ PAA Potassium Alum Block is a great deal. You’ll get a slightly smaller bar (3.4 ounces) than Gentleman Jon’s block, but it’ll only cost you $7. Plus, you’ll get a travel case with the PAA Potassium Alum Block. The major selling point for this block is that it has a rubber band grip to keep you from accidentally dropping it.

This bar, like all the others on this list, is made with potassium and has no herbs or fragrances. If you’re the type of person who needs a “legacy brand” product, then this block isn’t for you. Although Arizona-based Phoenix Artisan Accouterments has built up a big following in the past few years, it has only been around since 2012.

While this block might not be as elegantly designed as other products on this list, the PAA Potassium Alum Block is a great value. Beginners should seriously consider purchasing the PAA Potassium Alum Block for its ease of use.

3. Bloc Osma Alum Block

Price: $7.60.

Another popular potassium alum block is the Osma Bloc Alum Block. The French company Osma Rasage makes these blocks at their headquarters in the French commune Craponne. A 2.65-ounce block will set you back around $8 online. People who use this product say it’s the best alum block for people who want to experience a higher quality product for a low price. Since these alum blocks are handmade in France, it adds a certain “je ne sais quoi” to the product…if you’re into that.

The cardboard packaging is one of the prettiest in the industry, featuring a barber and his client in an old-fashioned Parisian barbershop. Osma Rasage has been producing high-quality shaving products since the 1950s, so you know you’re getting a product from a legacy company here. The only major downside to this alum block is that you don’t get a plastic case.

This could be a drawback if you do a ton of traveling. Also, the amount of alum block you get is less than the Gentleman Jon or PAA blocks. However, the Osma Bloc should last you many months after your purchase if you handle it with care.

4. Edwin Jagger Antiseptic Alum Block

Price: $12.00.

Made in Sheffield, England, the Edwin Jagger Antiseptic Alum Block is a high-end product great for people with sensitive skin. The main reason the Edwin Jagger block is considered higher quality has to do with its increased styptic effect. People who use this block are stunned by how well it closes pores and dries out the skin.

Whether you have dry or oily skin, the Edwin Jagger block will help quickly repair any shaving damage. The only real downside to this handmade product is the cost. A 1.9-ounce block will cost you around $12. This price does, however, include an elegant plastic travel block with a regal English logo.

5. Taylor of Old Bond Street Alum Block
