DIY Tested: Adjustable Guide & Soft Tool for Clean Necks - Versus Professional We've always been curious about how professionals manage that razor-sharp neckline. After some experimentation, we stumbled on the Neckline Shaving Template and Adjustable Hair Trimming Guide, a DIY tool that promises precision without the salon price tag. Made of soft, flexible material, it's gentle on skin and surprisingly easy to maneuver, even for beginners. The adjustable guide allows for custom tweaks, ensuring our necklines stay straight and neat-no more awkward dips or uneven edges. While it lacks the expertise of a barber, the system gives us control over our grooming, saving time and money. Plus, its compact design makes it travel-friendly. We found it slightly less forgiving than professional tools, requiring a bit of practice to perfect the angle, but the payoff is worth it for those who value independence. If you're tired of uneven neck hairlines, this might be the hack you've been waiting for-though we'll still admit, a pro's touch has its charm.
