Beauvoir Hair FAQ

  1. How long does the hair last?

    With proper care, Beauvoir hair typically lasts 9 to 16 months. Longevity varies based on shade, lifestyle, maintenance habits, and install method. Darker shades generally last longer due to less color processing.

  2. How soon can hair be washed after installing K-tips or Tape-ins?

    Please wait 48 hours after installation before your first wash to allow the bonds to fully set.

  3. What products should I use?

    Select a salon-grade shampoo and conditioner formulated without sulfates, keratin, or silicone. Sulfates are definitely the main ingredients to steer clear of, as they can dry out extensions. Also avoid labels that say bonding or clarifying as these will also dry out extensions. We have observed consistently strong performance with the Living Proof Restore Line, Pureology Hydrate Line, Davines (Oi products ONLY) and the Milbon Smooth Line. Even certain salon professional products can be too drying for extensions.

  4. What products should I avoid?

    Avoid products with sulfates, keratin, heavy silicones, clarifying shampoos and agents, and protein-heavy treatments. We do not recommend grocery/drug store shampoos and conditioners, as they often contain fillers and harsh detergents. Keep the routine simple: a high-quality, hydrating shampoo and conditioner and using a high-quality hair oil. We do not recommend Matrix shampoos and conditioners, Verb Ghost shampoos and conditioners, Davines Heart of Glass shampoo and conditioner, Redken All Soft, Milbon Repair Line or any type of clarifying shampoos or shampoos with sulfates as they will dry out the extensions and not provide enough moisture. Check ingredients in even salon professional products and avoid SULFATES at all costs (even many Salon Professional shampoos contain sulfates). These will strip moisture from extensions. We will not warranty hair that has used products with sulfates as it will destroy extensions. Use our product checker HERE to enter in your products and it will determine if they are extension safe. 

  5. Can I use hair masks or Keratin Treatments?

    We do not recommend hair masks. Many contain isopropyl alcohol, which can dry out the hair and cause brittleness or breakage. Use a lightweight leave-in conditioner or hair oil on mid-length to ends instead. We do not recommend any type of Keratin treatments on our extension hair. 

  6. Do you recommend a shower filter?

    Yes! Hard-water minerals and chlorine in water can reduce softness and shift tone, especially in blondes. A yellow color and brassiness in blondes is usually caused by minerals and chlorine in unfiltered shower water. To help preserve color we strongly recommend a shower filter. We recommend the Beauvoir Shower Filter. Replace the filter as needed (approximately every 3-4 months). Click HERE to check out our shower filter. 

  7. How fast do you ship?

    Orders placed before 3 p.m. Central Time on weekdays ship the same day. Orders placed after 3pm (CT) ship the next business day. We do not ship on weekends and scheduling delivery on weekends can be unpredictable. 

  8. Where is your hair sourced?

    Beauvoir uses only the top 10% of the healthiest hair available worldwide, which means we reject about 90% of the hair typically used in extensions. Our sourcing is extremely ethical; we work only with trusted partners in regions where hair donation is voluntary, fairly compensated, and culturally customary. Each bundle is evaluated for pH balance, moisture content, porosity, tensile strength, and average strand diameter. Before coloring, the hair is microscopically examined to assess cuticle health and determine the correct tone formulation. This ensures hair that blends naturally, maintains its softness, and wears beautifully over time.

  9. Is your hair 100% human hair?

    Beauvoir hair is 100% human hair with intact, naturally aligned cuticles. To preserve cuticle direction, the hair is braided before it is cut from the donor’s head. These braids are then sent, intact, to our factory. Because the hair remains braided, the natural cuticle alignment is clear and does not require the forceful re-alignment process commonly used in standard “remy cuticle” hair. This allows us to maintain the hair’s original cuticle integrity, resulting in extensions that stay softer, tangle less, and last significantly longer.

  10. Can the hair be colored by a stylist?

    Yes, our hair can be toned or colored. We have an online tutorial about how to color our extensions, which can be purchased here. However, lightening/bleaching can reduce longevity and discoloration and is not recommended.

  11. Can the hair be permed?

    Yes. We recommend the Oligo Pro OH6 perm system. Please test on a small section first. However ,we do also carry a wave texture in our Butterfly 20" extensions.

  12. Do you offer wavy or textured patterns?

    Yes. Textures are created using a controlled steam-setting technique. The wave texture is available in our 20" Butterfly Wefts.

  13. How long does the texture last?

    Our wave texture hair extensions last approximately 3–4 months with proper care.

  14. How many times can Forever Tape-ins/Tape Tabs be moved up?

    Typically 3–5 times, depending on maintenance and installation technique. We carry rolls of single and double sided replacement tape for these one piece tapes. We also carry replacement tape tabs.

  15. How much hair do I need?

    Volume Only: 1 row (40–100g) - one pack of genius, machine, tapes, or butterfly.

    K-Tips/I-Tips/Nano-Tips 1-2 Packs.

    Length + Volume: 2–3 rows (160–220g) 2 packs of genius (can use 3-4 wefts from the packs), 2 packs of tapes, one pack of machine, 3 packs of Forever Tapes. K-Tips/I-Tips/Nano-Tips 3-5 packs.

  16. How wide are your wefts?

    Butterfly Weft: ~13.25 inches. Genius Weft: ~40 inches (2 x 20 inch wefts/pack). Machine Weft: ~55 inches total. Forever Tape-ins: ~12 inches total.

  17. What is the difference between Pro Blend and Single Donor Virgin?

    Both Pro Blend and Single Donor Virgin are made using the top 10% healthiest hair. Previously, Pro Blend incorporated a portion of Remi cuticle hair, but we found that because Remi hair varies in cuticle integrity, it did not hold color with the same consistency as virgin hair. For this reason, Pro Blend has transitioned to being made entirely from virgin hair for consistent tone, softness, and longevity.
    Single Donor Virgin means that all of the hair in the weft comes from one individual donor. This creates subtle continuity in texture and movement. The performance is comparable between Pro Blend and Single Donor Virgin; the distinction is that Single Donor is considered a more exclusive, luxury option.

  18. Swimming & Water Exposure

    Salt water and chlorinated water can dehydrate the cuticle of both natural hair and extensions. Try to avoid hair contact with chlorine and salt water if possible. If swimming, wet the hair first with fresh water and apply a hydrating leave-in conditioner to create a protective barrier. Secure the hair in a braid or low ponytail to limit tangling.

    After swimming, rinse thoroughly with fresh water and apply conditioner. Do not allow salt or chlorinated water to dry into the hair. Rehydrating the hair after exposure maintains softness and movement.

    Swimming is possible with care. The key is to minimize exposure and restore moisture afterward.

  19. Heat Styling & Thermal Balance

    Extensions respond to heat similarly to natural hair. Excessive heat can cause dryness, roughness, loss of movement and discoloration. Use heat protectant without alcohol and keep hot tools at moderate temperatures, below 360 degrees Fahrenheit.

    Extensions hold shape well, so minimal heat is typically needed. Allowing the hair to cool in place helps maintain the style without repeated heat passes.

    Heat styling is normal. Moderation and protection preserve the cuticle and maintain longevity.

  20. Matting & Brushing Technique

    Hair extensions require regular brushing to maintain alignment. Matting most commonly appears when the hair is not brushed from roots to ends, particularly at the nape where movement and friction are highest. This is a normal behavior of human hair and does not reflect the quality of the extensions. Always ensure to part hair at rows in order to brush the natural hair between the rows, so the natural hair will not matte.

     

    Brush the hair in small sections, starting at the ends and working upward. Use a gentle detangling brush designed for extensions, and support the hair with your free hand to avoid tension at the scalp and attachment points. Consistent, intentional brushing maintains smooth cuticle alignment and prevents tangling.

    Sleeping with the hair in a loose braid or low ponytail reduces friction and helps maintain longevity.

  21. Dryness & Moisture Balance

    Beauvoir hair is not dry when it leaves the factory or our warehouse. Each bundle is measured for moisture content before sourcing and again before finishing. We only select hair that measures between 12% and 18% moisture, which is the ideal range for intact, healthy cuticles. Hair outside this range is not purchased.

    If dryness develops after installation, the cause is almost always product interaction. Some shampoos, conditioners, and masks, even salon-grade ones, are not suitable for extensions due to their protein content, pH level, or silicone type. If dryness occurs, the first step is to adjust the product regimen - change out ALL your products!

    We recommend Davines (Oi line) or Milbon as reliable hydration systems. A high-quality hair oil can also be used to restore softness and moisture. After adjusting products and rehydrating, the hair should return to its natural texture and movement. Please be aware that a yellow colored hair oil will eventually turn blondes yellow, so opt for a clear hair oil.

  22. Shedding & Natural Hair Behavior

    Human hair naturally sheds. Extensions will shed as well. Slightly increased shedding is normal immediately after installation, especially where a machine weft has been cut for placement.

    To minimize shedding at the cut point, the weft should be cut from the top down, and the cut should be straight. Cutting upward into the hair or cutting on a diagonal can increase shedding at the seam. We also recommend applying Fray Check to the cut ends on our machine wefts to minimize initial shedding at the cut points.

    Normal shedding is expected within the first month after install (especially with our machine wefts). Excessive shedding, where the weft loses a noticeable amount of its density, is not expected. 

  23. Sunscreen Exposure

    Ensure that hair extensions do not come into contact with chemical sunscreens containing ingredients such as avobenzone and/or octocrylene. This can happen when hair brushes against sunscreen applied to the skin or when spray sunscreen settles onto the extensions. Exposure to these chemicals may cause discoloration, often turning the extensions a pink or orange hue. We recommend mineral sunscreen as it will not discolor the hair.
