DS Laboratories Spectral Extra Strength 7% Nanoxidil + 3 DHT Inhibitors Serum (60ml)

Spectral Extra Strength is DS Laboratories' most advanced topical serum - built for those dealing with more significant thinning who need a formula that matches the challenge. At 7% Nanoxidil, the highest concentration DS Laboratories offers, it combines their most potent proprietary active with 3 natural DHT inhibitors and 28 carefully selected ingredients, all delivered via the Advanced Nanosome Delivery System for deep, sustained follicle-level action. It also addresses the appearance of grey strands - a rare combination of density and vibrancy support in a single daily serum.

Spectral Extra Strength is for anyone experiencing more advanced hair thinning who wants the strongest available Nanoxidil formulation. It's equally suited to those looking to address both density and the early appearance of grey - and works best as part of a complete DS Laboratories routine alongside Revita Shampoo and Conditioner. Suitable for sensitive scalps. Propylene glycol-free.

• 7% Nanoxidil - DS Laboratories' highest concentration - targets advanced thinning with superior follicle absorption
• Three natural DHT inhibitors work synergistically to address the root cause of androgenic hair loss
• Supports visibly thicker, fuller hair with improved scalp coverage in as little as 90 days
• Helps diminish the appearance of grey strands by supporting melanin production
• Minimizes shedding and promotes a more robust hair growth cycle
• Lightweight, water-based, non-greasy formula - propylene glycol-free and suitable for sensitive scalps 

• Nanoxidil 7% - DS Laboratories' proprietary active at its highest available concentration, engineered for maximum follicle absorption and superior results in advanced thinning.
• Saw Palmetto (Serenoa Serrulata Fruit Extract) - One of three natural DHT inhibitors in the formula, Saw Palmetto helps address androgenic hair loss at the hormonal level by blocking DHT activity at the follicle.
• Acetyl Tyrosine & N-Acetyl Tyrosine (Acetyl Tyrosine) - Supports melanin production in the hair shaft, helping to diminish the visible appearance of grey strands over time.
• Palmitoyl Tetrapeptide-20 - A targeted peptide that supports follicle anchoring proteins and promotes a healthier, more resilient hair growth cycle.
• Acetyl Tetrapeptide-3 - Works alongside Palmitoyl Tetrapeptide-20 to strengthen the follicle environment and reduce shedding at the root level.
• Clover Flower Extract (Trifolium Pratense Flower Extract) - A natural isoflavone-rich DHT inhibitor that complements Saw Palmetto's action, supporting scalp health and follicle longevity.
• Niacinamide - Supports scalp cellular function and reduces inflammation, creating a healthier foundation for the formula's actives to work from.

Apply directly to the scalp in areas of concern - not to the hair lengths. Use the applicator to distribute evenly across the scalp. Gently massage in with fingertips to aid absorption. Do not rinse. Leave on and style as usual. For best results, use twice daily - morning and evening. Allow 90 days of consistent use before assessing results, with peak results typically seen around 180 days.

When the standard Spectral isn't enough, Extra Strength is the answer. The jump from 5% to 7% Nanoxidil is meaningful - and the addition of three DHT inhibitors and peptide actives makes this the most comprehensive topical treatment in the DS Laboratories lineup. For anyone committed to a serious thinning hair routine, this is the strongest daily serum we carry.
