How does the 21B design improve comfort during shaving?

The 21B head combines a three-blade floating mechanism with a fine, skin-friendly foil to minimize pulling and reduce surface friction. The floating cutters adapt to facial contours for even contact, while the comb teeth help lift stubble for a more even cut. These features lower the risk of tugging and make both dry and wet shaves more comfortable.

• Floating three-blade system for contouring
• Precise comb teeth lift hairs for cleaner cutting
• Silver foil material reduces surface irritation

Can I use this replacement head for wet and dry shaving?

Yes — the AIJALY Series 3 21B head is designed for dual-purpose use, performing well in quick dry shaves and in wet shaves with foam or gel. The construction resists water exposure and keeps cutting efficiency consistent, allowing you to choose the approach that fits your routine. After replacement, many users regain near-original shaving performance and smoother results.

• Works with shaving foam, gel, or dry use
• Durable foil maintains effectiveness under moisture
• Restores up to 99% of original performance when replaced

What maintenance or replacement schedule should I follow?

Regular inspection and timely replacement keep your shaver cutting well and reduce skin discomfort from dull blades. Replace the head if you notice tugging, uneven cutting, or increased irritation. Rinse after use, allow to dry, and replace according to your hair growth and usage frequency to maintain optimal results.

• Rinse under running water after each use and air-dry
• Replace when cutting performance decreases or irritation rises
• Typical replacement interval varies by user but inspect every few months
