how often should you change your razor

You should change your razor blades generally after every 5 to 7 shaves for a smooth and safe shave. However, this varies depending on the razor type and shaving frequency. For example, 5-blade razors can last about 20 shaves, 3-blade razors about 15 shaves, and daily shavers are advised to change blades weekly. Signs you need a new blade include a dull feel, more irritation, pulling on hairs, or the lubricating strip fading. Using dull blades can cause cuts, irritation, and infection, so regular replacement is important for hygiene and comfort.
