Is this kit right for me?

If you answer YES to any of these, the Repair & Restore Kit is what your hair needs.

Damaged by bleach, colour or heat

Feels dry, rough or straw-like

Breaks easily or has fragile ends

Tangles or becomes frizzy quickly

Rebuild what’s broken. Replace what’s lost. Protect what’s left.

Repair - rebuilds hair from within Repair - rebuilds hair from withinPlex Treatment

Bleach, colour, heat styling and everyday environmental stress can weaken the internal bonds that keep hair strong. Our Plex Treatment targets this damage, helping to rebuild broken bonds and strengthen weakened hair - leaving it healthier, more manageable and less prone to breakage.

Restore - replenishes lost moisture Restore - replenishes lost moistureDeep Conditioning Mask

Damage can strip hair of the moisture it needs to feel soft and healthy. Our Deep Conditioning Mask delivers intensive moisture and nourishment, transforming dry, rough, straw-like hair into softer, smoother and more manageable strands.

Seal - the finishing layer Seal - the finishing layerHair Oil

Our Hair Oil seals moisture into the hair and smooths vulnerable lengths and ends, helping to protect your Repair & Restore results while guarding against dryness, tangling, breakage and further damage. Hair is left smoother, softer and easier to manage.

This is a repair system. Not another hair mask.

PLEX TREATMENT

Formulated with Hydroxypropylgluconamide and Hydroxypropylammonium Gluconate. Sustainably sourced, bio-based molecules that penetrate the hair cortex and bond directly to its internal protein structure. Rebuilding strength from the inside out.

DEEP CONDITIONING MASK

Packed with seven nourishing plant extracts (rosemary, nettle, birch, horsetail, coltsfoot, yarrow, wild thyme), plus hydrolyzed proteins and panthenol to replenish moisture and reinforce hair from root to end.

HAIR OIL

Rich in fatty acids and vitamin E, these lightweight oils (sweet almond, grape seed, argan and jojoba) nourish, add shine and seal in moisture without weighing hair down.

Your Repair & Restore Routine

Three simple steps to stronger, softer, healthier-looking hair.

1

FIRST WASH: Use Plex Treatment

After shampooing, saturate wet hair with Plex. Comb through, leave for at least 30 minutes, then rinse.

2

NEXT WASH: Use Deep Conditioning Mask

Apply to wet lengths and ends after shampooing. Leave for 10-30 minutes, then rinse. Alternate with Plex each wash*.
*As hair strengthens & breakage reduces, use Plex every third or fourth wash and the Mask in between.

3

Hair Oil: daily or whenever your ends feel dry.

Smooth 1–3 drops through the lengths and ends of dry or damp hair.

Frequently Asked Questions

How often should I use each product?

Use the Deep Conditioning Mask every wash day, the Plex Treatment every fourth wash, and the Hair Oil daily or whenever your lengths and ends feel dry.

Do I need to use all three products together?

The products work best as a complete repair routine, but you do not need to use all three every time. On Plex days, follow with the Mask if your hair still feels rough or tangled, then finish with Hair Oil once dry.

Will the products weigh down fine hair?

If you have fine hair, start with a small amount of the Mask and just a few drops of Hair Oil. Concentrate on the mid-lengths and ends, adding more only when your hair needs it.

How quickly will I see results?

Your hair should feel softer, smoother and easier to manage after the first use. With consistent use, damaged hair should begin to feel stronger, healthier and less prone to breakage over time.

WHY ABI MADE THIS

“When hair has been damaged by bleach, colour or heat, it often needs more than just moisture. I created the Repair & Restore Kit to bring together everything your hair needs in one simple routine.

The Plex Treatment helps strengthen weakened hair, the Deep Conditioning Mask restores lost moisture, and the Hair Oil seals it all in and protects dry ends. Used together, they help damaged hair feel stronger, softer and much easier to manage.”
