Hair Line Booster Shot

For thinning hairlines and weakened roots.

A targeted scalp ampoule for the area most people notice first when hair starts to thin, the hairline and temples. The formula pairs S-PDRN (a smaller, more absorbable form of PDRN) with patented Escin to support scalp circulation, plus biotin, caffeine, and rosemary to nourish roots. What makes it different from a standard scalp serum is the delivery system: 20,000 micro-spicules (ultra-fine sponge-derived particles smaller than your pores) that gently press into the scalp to help the actives absorb up to three times more effectively.

The texture is watery and lightweight, with a slight cooling finish from the menthol. The roll-on tip lets you apply it directly along the hairline without making a mess, and you can lock the bottom of the bottle to prevent leaking which matters for something this concentrated. Brand testing claims visible results in around 10 days with daily use.

Best For: Anyone noticing a widening hairline, thinning at the temples, or weakened roots; also a good preventive step if you're starting to see early signs of thinning and want to act before it progresses.

Key Ingredients
S-PDRN A smaller, more absorbable form of PDRN that helps support scalp regeneration and root strength. Escin (Patented Complex) A botanical active that supports scalp blood circulation, doubled in this formula for stronger results. Micro-Spicules Ultra-fine sponge-derived particles that gently exfoliate and create micro-channels so active ingredients absorb deeper. Biotin and Panthenol A nourishing duo that supports stronger, healthier hair from the root. Caffeine, Rosemary and Niacinamide A scalp-stimulating trio that supports circulation, clarity and a healthier root environment.
How to Use
Twist the bottom button to unlock the bottle, then click to dispense the product. Roll directly along your hairline and any thinning areas, gently massaging in. After use, twist the button back to lock. Use 1–2 times daily, ideally before bed on a fully dry scalp for best absorption. Tip: Apply to a fully dry scalp — moisture on the surface will dilute the actives and reduce absorption. If you've just washed, wait until your scalp is completely dry before using.
