Step-by-Step Hair Extension Care Routine
Gently cleanse with sulfate-free shampoo to remove buildup without drying your extensions.
Apply hydrating conditioner mid-length to ends. Avoid roots and attachment points.
Use a leave-in conditioner after washing to smooth and moisturize your extensions daily.
Lock in shine and hydration with a lightweight oil or serum.
Always apply a thermal protectant before using any hot tools.
Choosing the Right Shampoo
Start with the right shampoo. Choose formulas that are free of sulfates, parabens, and sodium chloride. These harsh ingredients strip natural oils, weaken the cuticle, and shorten your extensions’ lifespan. Instead, look for nourishing ingredients like protein, keratin, amino acids, and vitamin B5 — these strengthen extensions, maintain elasticity, and add shine.
We recommend Cuticle Lisse Hair Extension Shampoo, specifically designed to protect and hydrate extension hair.
How Often Should You Wash Extensions?
Wash your extensions 1–2 times per week. If you have oily hair, you can wash every other day — but remember, the less you wash, the longer your extensions will last. High-quality extensions can last up to one year when paired with gentle products like Cuticle Lisse Conditioner.
Choosing the Best Conditioner
Conditioning is one of the most important parts of extension care. Because your extensions don’t receive scalp oils, use conditioners that deeply hydrate without harsh chemicals.
We recommend:
Rebuilds and strengthens hair in just 60 seconds with silk proteins and botanical extracts.
Seals the cuticle, reduces frizz, and smooths texture for curly or coarse hair types.
Weekly Deep Conditioning Treatment
In addition to your regular routine, use a deep conditioning treatment every 1–2 weeks. We recommend the Cuticle Lisse Argan Oil Deep Conditioning Masque — infused with shea butter and Moroccan argan oil to restore elasticity, rebuild strength, and rehydrate dry or damaged extensions.
Daily Styling and Heat Protection
After washing, apply a lightweight argan oil serum to keep your extensions smooth, shiny, and frizz-free. Always use a thermal defense spray before blow drying, curling, or straightening to prevent heat damage.
Final Thoughts
Knowing how to take care of hair extensions is the key to getting the most from your investment. The right care routine will keep your extensions looking flawless and protect your natural hair from damage. Cuticle Lisse products were designed specifically to hydrate, repair, and extend the life of your extensions.
Frequently Asked Questions: How to Take Care of Hair Extensions
What is the most important step in taking care of hair extensions?
If there’s one non-negotiable in knowing how to take care of hair extensions, it’s daily brushing. Extensions don’t receive the natural oils your scalp produces, which means they rely entirely on what you add through products — and they tangle faster than natural hair without regular detangling. A soft-bristle paddle brush used from the ends upward each morning prevents the small knots that form overnight from becoming large matted sections near the track. Five minutes of brushing every day dramatically extends the life and condition of your extensions.
How do I wash hair extensions without damaging them?
To properly wash your extensions, wet your hair thoroughly with warm water, then apply a small amount of sulfate-free shampoo from root to mid-length. Gently massage the scalp and let the shampoo rinse downward through the extension hair — don’t scrub the extension hair itself in a circular motion, as this causes tangling. Rinse completely, then apply conditioner to the mid-length and ends only, avoiding the attachment points and beaded track. After washing, gently squeeze excess water from the extensions rather than wringing or twisting, and brush out gently while still damp.
Do I need special products to take care of hair extensions?
You don’t necessarily need extension-specific products, but you do need to choose products carefully. The requirements are: sulfate-free shampoo, moisturizing conditioner, a leave-in conditioner or detangling spray, a lightweight oil or serum for daily moisture, and a heat protectant for styling. Avoid anything containing sodium chloride, heavy alcohols, or harsh chemicals. Glamour Locks offers the Cuticle Lisse product line — formulated specifically for how to take care of hair extensions using cuticle-aligned human hair.
How do I protect my hair extensions while sleeping?
The easiest way to protect your extensions overnight is to loosely braid your hair before bed. This prevents the extension hair from rubbing against your pillow and forming knots during sleep. If you prefer not to braid, a loose bun secured with a snag-free hair tie is a good alternative. Sleeping on a satin or silk pillowcase significantly reduces friction compared to cotton. Never sleep with your hair in a tight style — this creates tension at the attachment points that can cause soreness and breakage at the track over time.
How often should I deep condition my hair extensions?
Once a week is the standard recommendation for most Glamour Locks clients. A weekly deep conditioning treatment applied to the mid-length and ends for 10 to 20 minutes replenishes the moisture that washing and everyday wear remove. For clients who heat style frequently, swim regularly, or live in dry climates, twice-weekly deep conditioning may be more appropriate. Use a protein-free, moisturizing mask for regular conditioning, and reserve protein treatments for once a month. Over-use of protein on already-healthy extensions can make the hair feel stiff and brittle — learning how to take care of hair extensions means understanding this balance.
Building a Complete Hair Extension Care Routine: Month by Month
Knowing how to take care of hair extensions is one thing — actually building it into a consistent routine is another. The clients who get the best long-term results treat their extension care routine as a non-negotiable part of their day, not something they do when they remember. Here’s how to think about the routine across the full wear cycle.
The Daily Routine (5–7 Minutes)
Every morning, before doing anything else with your hair, run a soft-bristle extension brush through your extensions starting from the ends and working upward to the roots. This takes two to three minutes and prevents small tangles from becoming large knots. If your hair feels dry or static, apply two to three drops of a lightweight serum through the mid-length and ends before brushing. In the evening before bed, loosely braid your hair — a single low braid is sufficient — to prevent overnight tangling and friction against your pillow. This five to seven minute daily investment is the foundation of knowing how to take care of hair extensions effectively.
The Washing Routine (Every 2–3 Days)
Washing frequency matters as much as washing technique for extension longevity. Every two to three days is the optimal interval for most clients — frequent enough to keep the scalp clean and prevent product buildup at the track, but not so frequent that the extension hair is stripped of moisture with every wash. When washing, use a sulfate-free shampoo applied at the scalp and allowed to rinse through the extension hair rather than scrubbing the extensions directly. Follow with a moisturizing conditioner on the mid-length and ends, leaving it on for two to three minutes before rinsing. Finish with a leave-in conditioner spray throughout the extension hair before brushing out gently with a wide-tooth comb while still damp.
The Weekly Treatment (20–30 Minutes)
Once a week, replace your standard conditioner with a deep conditioning mask. Apply generously from mid-length to ends, clip the hair up, and leave on for 20 to 30 minutes before rinsing. This weekly treatment is what keeps extension hair supple, smooth, and manageable throughout the full wear cycle. Clients who do this consistently notice that their extensions feel softer and brush out more easily at month nine than clients who rely on regular conditioner alone. The weekly treatment adds only 20 minutes to the routine and has an outsized impact on how long do hair extensions look and feel their best.
The Monthly Check-In
Once a month, examine your extensions more carefully than your daily routine allows. Run your fingers along each row to check that the beads are sitting securely and haven’t shifted position. Look at the ends of the extension hair — are they smooth or beginning to show signs of dryness and splitting? Check your natural hair at the scalp around the track for any signs of buildup or irritation. If anything seems off, contact your Glamour Locks stylist for an assessment rather than waiting for your scheduled retightening. Monthly self-checks catch minor issues before they become major ones and are an underutilized part of how to take care of hair extensions properly.
The Six-Week Retightening: What to Expect and How to Prepare
Come to your retightening appointment with clean, brushed hair — wash the day before if possible. The appointment begins with your stylist examining the condition of the wefts and the track, then briefly removing the weft from each row, sliding the beads back up to the current scalp position, and re-sewing the weft onto the adjusted track. The Tension Strap is reapplied, and the appointment concludes with a quick check of the blending at the ends. Most retightening appointments take 45 minutes to an hour. After the appointment, treat your hair gently for 24 hours as the track settles into its new position — normal washing and brushing can resume the following day.
