AG Reconstruct Vitamin C Strengthening Mask is a rich rinse-out treatment that leaves hair stronger, shinier and more radiant, made with vitamin C, plant-based squalane and shea butter. It comes in a 178 ml (6 fl oz) tube and belongs to AG's Vita C repair family alongside the Vita C Strengthening Shampoo and Conditioner.

The vitamin C is a stable, oil-soluble form (tetrahexyldecyl ascorbate). Squalane and Abyssinian seed oil add softness and slip, while shea butter and fatty alcohols give the mask its thick, cushioning texture. Conditioning agents, including amodimethicone, smooth the surface of the hair so it combs out easily and reflects more light.

Massage it into damp hair after shampooing and leave it on for five minutes before rinsing, or longer for more intensive conditioning.

  • Intense nourishment for dry, stressed or brittle hair
  • Strengthens and adds shine
  • Five-minute treatment, or leave longer for more conditioning
  • Contains no keratin, and is fine to use on keratin-treated hair

Free of drying sulfates, vegan and cruelty-free, like all AG formulas.

Hair that feels dry, rough, brittle or over-processed, whether from colour, heat styling or chemical services, and needs more conditioning than an everyday conditioner gives. AG customers report using it on fine, curly and coily hair alike.

AG confirms it contains no keratin and can be used on keratin-treated hair. It's a retail treatment for home use and is also used in salons.

Reconstruct is the treatment step in AG's vitamin C repair routine. Its stable vitamin C, squalane and shea butter are paired with strong conditioning agents, so a single five-minute application makes dry, rough hair noticeably softer, smoother and shinier, and leaving it on longer gives a deeper conditioning without needing a separate product. Being keratin-free also makes it an easy fit for people maintaining a keratin smoothing treatment.

  • Shampoo, then gently squeeze excess water from the hair.
  • Massage the mask into damp hair, concentrating on mid-lengths and ends.
  • Leave on for 5 minutes, or longer for more intense conditioning.
  • Rinse thoroughly and style as usual.

Pros:

  • Thick, rich texture that gives a lot of slip for detangling
  • Quick five-minute treatment, with the option to leave it longer
  • Keratin-free, and safe on keratin-treated hair
  • Rinses out after five minutes, so it fits into a normal wash routine

Cons:

  • Can feel heavy on fine or oily hair if over-applied; keep it to mid-lengths and ends
  • Contains silicones and fragrance, so it doesn't fit silicone-free routines
  • At 178 ml, heavy weekly users on long hair will go through a tube quickly
