Square Root

Volumizing Root Serum.

For Fine, Thinning Hair.

  • Description
  • Ingredients
  • Directions

Thick hair begins with a healthy scalp, and this pH balanced serum plants the seed for dense, gorgeous hair. Square Root Serum nourishes your roots and restores pigment to gray hair naturally (with no dyes). DHT-blockers inhibit hormonal hair fall and natural prebiotics promote a healthy scalp. This is a safe, natural alternative to Minoxidil (hair loss drug).


2 fl oz | 59 ml

Ingredients: Water (Aqua), Polysorbate 20, Hydrolyzed Lupine Protein, Lactobacillus Ferment, Melaleuca Alternifolia (Tea Tree) Leaf Water, Sodium Hyaluronate, Glycerin, Yeast Extract, Acetyl Tyrosine, Glycine, Larix Europaea Wood Extract, Zinc Chloride, Panthenol, Caffeine, Glucosamine HCl, Aloe Barbadensis Leaf Juice, Rosa Damascena Flower Water, Camellia Sinensis Leaf Extract, Hamamelis Virginiana (Witch Hazel) Bark/Leaf/Twig Extract, Serenoa Serrulata Fruit Extract, Arginine HCl, Sodium Metabisulfite, Menthyl Lactate, PEG-40 Hydrogenated Castor Oil, PPG-26-Buteth-26, Maltodextrin, Fragrance, Phenoxyethanol, Ethylhexylglycerin, Sodium Benzoate, Potassium Sorbate, Sodium Hydroxide, Benzyl Salicylate, Limonene, Hexyl Cinnamal, Hydroxycitronellal, Linalool, Alpha-Isomethyl Ionone

Directions: Use targeted sprayer to direct the product at your roots. Use daily. Massage in well for best results. Due to volumizing and thickening ingredients, your hair may dry with a thickening film. If you have fine or straight hair, release the film by brushing dry hair at the roots with a fine bristle brush. If you have curly hair, loosen with a wide tooth comb or fingers once dry. This will help volumize your roots.

How does it work?

Square Root supplies oxygen and nutrients to vascular system to support & revise the dying follicle. Restores pigment to gray hair naturally (with no dyes) over time for thicker looking hair. Square Root also fights inflammation . Ever seen hair grow on a scar? It can't, because the hair follicles have scarred over from inflammation. The same thing happens if your scalp is inflamed. Follicles grow narrower and narrower until hair can no longer grow.
