Anti-aging experts emphasize the importance of regular scalp rejuvenation treatments to prevent skin sagging and wrinkles, as the scalp ages up to 20 times faster than facial skin. This accelerated aging is primarily due to chemical treatments like hair dyes and harsh ingredients like SLES and parabens, combined with a lack of proper scalp moisturizing. Focusing only on facial skincare is insufficient, as these factors can lead to premature scalp aging, which contributes to overall skin sagging and wrinkles.
