No matter how fast your hair grows, split ends are an annoying obstacle between you and your long-hair goal progress. This deeply nourishing oil revives and mends split ends, enabling you to grow your hair longer without trimming away damage so frequently. This sustainable, sugar-derived oil repairs damaged cuticles for strong, glossy, frizz-free hair.


2 fl oz | 59 ml

Ingredients: C13-15 Alkane, Caprylic/Capric Triglyceride, Squalane, Tetrahexyldecyl Ascorbate, Oryza Sativa (Rice) Bran Extract, Rosmarinus Officinalis (Rosemary) Leaf Extract, Helianthus Annuus (Sunflower) Extract, Tocopherol, Fragrance, Benzyl Salicylate, Limonene, Hexyl Cinnamal, Hydroxycitronellal, Linalool, Alpha-Isomethyl Ionone

Directions: For Oily/Normal Hair: Apply sparingly to damp hair shaft and ends. Avoid roots. Style as usual. For Dry/Frizzy Hair: Apply generously on damp or dry hair, focusing on shaft and ends.

We are going to extra lengths to make sure your vacation hair is nothing short of fabulous.

Traveling just got a whole lot sweeter this summer with our June Promo, a FREE travel-sized Density with any order of Sugar Pi. These two products work together to deeply nourish and revive your hair to ensure healthy, beautiful locks.


We know how damaging the pool, beach, and sun can be to your hair. This duo works together to prevent damage from occurring by strengthening your strands and sealing the cuticles. You won't want to forget these two hair heroes in your toiletry bag! They really know how to save the day.


The best part is if you are flying both products are TSA carry-on approved!

Sugar PiNo matter how fast your hair grows, split ends are an annoying obstacle between you and your long-hair goal progress. This deeply nourishing oil revives and mends split ends, enabling you to grow your hair longer without trimming away damage so frequently. This sustainable, sugar-derived oil repairs damaged cuticles for strong, glossy, frizz-free hair.


DensityThere’s one very important cause of hair loss that is always overlooked: hair breakage. Weak strands with damaged cuticles break easily and hair just can’t grow long or thick. Theorem Density Mask repairs the hair cuticle to promote hair retention. The advanced, silicon-infused formula plumps up hair strands like an injectable filler. Works synergistically with heat to strengthen and thicken hair strands, giving you the length and shine you deserve.
