Difeel Biotin Hair Growth Regimen 4-PC Set — Shampoo, Conditioner, Leave-In & Oil, Color-Safe Strengthening

Difeel Biotin Regimen for Hair Growth is a four-step shampoo, conditioner, leave-in spray and premium hair oil system designed to strengthen strands and support fuller-looking hair.

This complete set combines biotin-enriched cleansing, conditioning, lightweight leave-in treatment and a concentrated oil to help improve the appearance and manageability of hair. The formula is sulfate-, paraben- and phthalate-free and safe for color-treated hair, offering a routine you can use daily without harsh surfactants.

How does the four-step system work together?

Each product targets a different part of your routine so they layer without weighing hair down. The shampoo cleanses and primes, the conditioner smooths and detangles, the leave-in spray adds lightweight protection and the oil seals and polishes ends.

• Step 1: Biotin Pro-Growth Shampoo — gentle cleansing base that removes buildup.
• Step 2: Biotin Pro-Growth Conditioner — detangles and improves comb-through.
• Step 3: Biotin Pro-Growth Leave-In Spray — heat-friendly, light conditioning boost.
• Step 4: Biotin Premium Hair Oil — concentrated nourishment for ends and shine.

What benefits can I expect when using these products together?

The regimen focuses on strengthening and improving hair body and texture over time. Regular use supports fuller-looking hair and reduces breakage by improving manageability and moisture balance.

• Strengthening support with biotin-infused formulas for improved strand resilience.
• Fuller appearance from smoother, less frizzy hair and enhanced shine.
• Color-safe, gentle ingredients suitable for treated hair.

How should I use each item in my daily or weekly routine?

Start in the shower with the shampoo and conditioner, then apply leave-in spray on damp hair followed by a small amount of oil on mid-lengths and ends. Adjust oil frequency depending on hair porosity and styling needs.

• Shampoo: apply to wet hair, massage, rinse thoroughly.
• Conditioner: apply mid-lengths to ends, leave 1–3 minutes, then rinse.
• Leave-In Spray: mist on damp hair before styling or heat tools.
• Hair Oil: work a few drops through ends; use sparingly to avoid buildup.

Is this set safe for colored, chemically treated or textured hair?

Yes — the formulas are designed to be color-safe and free of sulfates, parabens and phthalates. The lightweight leave-in and oil accommodate a range of hair types from fine to coarse when used in appropriate amounts.

• Color-safe: balanced surfactants and no harsh sulfates.
• Free from parabens and phthalates for gentler daily use.
• Works on straight, wavy, curly and coily textures with proper portioning.

Who this is for: the Difeel Biotin Regimen 4-step set is made for anyone seeking a complete at-home routine to support stronger, more manageable hair—especially people who want biotin-fortified care without harsh sulfates or parabens. It suits those with color-treated or chemically processed hair and anyone looking to add a structured, easy-to-follow program that combines cleansing, conditioning, lightweight protection and targeted oiling for improved hair appearance.
