Biolage Full Rescue Invigorating Serum – 1.6 fl oz leave-in scalp treatment with rosemary & niacinamide for stronger, color-safe h

Biolage Full Rescue Invigorating Serum is a daily leave-in scalp serum formulated with steam-distilled rosemary oil and niacinamide to fortify strands and support a healthier scalp.

This lightweight, micro-dosed serum is part of the Full Rescue system and is designed to be applied to a towel-dried scalp after shampoo and conditioner. It combines rosemary oil and triple-purified niacinamide to help increase moisture retention at the scalp, strengthen hair from root to tip, and improve resistance to hair breakage from mechanical stress. The formula is suitable for color-treated hair and intended for regular use as a leave-in treatment.

How will this serum fit into my existing hair routine?

Use the Full Rescue Serum after cleansing with Full Rescue Shampoo and Conditioner for best results. Apply directly onto a towel-dried scalp, massage in, and style as usual — no rinse required. Consistent daily application is recommended to support visible improvements.

• Apply a single drop per inch across the scalp for even dosing
• Massage gently to encourage absorption and circulation
• Comb through to distribute product along strands
• Leave in; style without rinsing

What active ingredients does it use and what do they do?

The serum centers on steam-distilled rosemary oil and highly purified niacinamide working together to nurture scalp balance and strand resilience. Rosemary helps invigorate the scalp while niacinamide supports moisture retention and fortifies the hair shaft, contributing to stronger-looking hair over time.

• Steam-distilled rosemary oil: soothes and invigorates the scalp
• Triple-purified niacinamide: supports moisture balance and strand strength
• Micro-dosed formulation: lightweight, non-greasy daily use
• Safe for color-treated hair

How quickly will I notice changes in my hair?

Individual results vary, but improvements in manageability and strand resilience can be observed with regular use. The Full Rescue system (shampoo + conditioner + serum) has shown stronger, longer-looking hair within weeks when used consistently.

• Daily application supports cumulative benefits
• System use (shampoo + conditioner + serum) maximizes results
• Expect gradual improvement in thickness and strength with continued use

Is this serum suitable for my hair type and concerns?

Formulated for fine, thinning, or weakened hair, the serum helps support scalp health and improve hair resilience without weighing strands down. It's safe for color-treated hair and works as a complement to other styling or treatment products.

• Ideal for fine, fragile, or thinning hair
• Compatible with color-treated or chemically processed hair
• Lightweight texture suitable for daily leave-in use
• Can be combined with styling products and treatments

Who this is for: Biolage Full Rescue Invigorating Serum suits anyone looking to support scalp balance and strengthen fragile strands — especially those with fine or thinning hair seeking a lightweight, leave-in option. If you want to integrate a targeted fortifying step into your daily routine while maintaining color-treated hair, this serum is designed to deliver supportive nourishment without residue.
