  • Adds volume effectively, especially for baby fine, thin hair.
  • Leaves hair shiny, soft, and full throughout the day.
  • Sufficient lather for a sulfatree shampoo, easier rinsing.
  • Provides a thick, lustrous, and bouncy full head of hair.
  • Gives a 'squeaky clean' feel, ideal for baby fine hair.
  • Hair feels soft without excessive slipperiness, maintaining body and texture.
  • Only a quarteized amount is needed for full use, making it last longer.
  • Effectively supports hair health, especially for thinning hair.
  • Does not weigh hair down, enhancing hair fullness and thickness.
  • Works well when used alone without conditioner or additional products for short hair.

Cons

  • Some concerns if it will maintain volume with repeated washing.
  • Noted as somewhat pricey.
  • Pleasant new spicy scent may be too strong for some and is lonasting.
  • May not be effective for individuals with longer hair or those frequently using styling products, as it may require a large quantity to achieve cleanliness.
  • Occasional issues with removing product buildup after using heavy styling aids.
  • Alternating with other shampoos is recommended for those with fine but dense hair, as it sometimes makes hair appear too voluminous.

Bottom Line

If you're looking for a shampoo that effectively adds volume to fine, thin hair and leaves your locks shiny and soft throughout the day, the R+Co Dallas Biotin Thickening Shampoo could be a great choice. While it comes with a somewhat higher price tag and a strong, spicy scent that may not appeal to everyone, it requires only a small amount per wash, potentially offering longer use. For those with longer hair or who use heavy styling products, an alternative or supplementary product could be worthwhile.
