If you want stronger hair, build a routine that strengthens the inside and smooths the outside. Chemical services, heat, rough brushing, tight styles, and hard water chip away at bonds, protein scaffolding, and the lipid layer on the cuticle. FILAMENT sits at the center of this plan as your primary hair strengthening treatment. Around it, you add light protein when elasticity calls for it, deep conditioning for slip, chelation for mineral control, and heat discipline. This combination stops daily micro-damage, reduces breakage, and makes hair easier to style.

The Core Idea

Hair breaks for two reasons. Inside, bond and keratin damage weaken fibers. Outside, a rough cuticle raises friction so strands snag and snap. FILAMENT supports internal strength while restoring surface slip, which is why it is the anchor for every hair type in this playbook.

Quick Self-diagnosis

Use how hair behaves, not guesswork.

• Mushy and stretchy when wet, then it snaps during combing - you likely need a mild protein reconstructor in addition to Filament.
  
  

• Rough, squeaky, tangly even after conditioning - you need a richer mask and friction control, with Filament providing the strength base.
  
  

• Weakness after bleach or color that loses shape fast - you need weekly FILAMENT sessions as bond and strength support.
  
  

• Breakage concentrated on crown or hairline - you need lower heat, fewer passes, and targeted Filament coverage on high wear zones.
  
  

The Weekly Routine that Actually Works

Follow this exact order for four weeks. It keeps the fiber receptive and avoids product pileups.

1. Pre-shampoo buffer - once per week if hair is porous
   Apply a thin coat of oil on mid-lengths and ends for 30 to 60 minutes, then shampoo and condition. This reduces protein loss during washing and lowers friction before you add FILAMENT later in the week. If hair is fine and easily weighed down, skip or use a tiny amount.
   
   

2. FILAMENT strengthening session - once per week as the anchor
   Cleanse, gently squeeze out water, then apply FILAMENT in sections from mid-lengths to ends. Comb through for even coverage, leave on as directed, rinse thoroughly, and detangle under running water. Judge progress by easier detangling and fewer snapped ends, not just shine.
   
   

3. Protein reconstructor - once every 2 to 4 weeks only if elasticity demands it
   If a wet strand stretches like taffy before breaking, add a mild reconstructor this week. Rinse well and follow with a softening conditioner. If hair feels stiff or dull after drying, reduce protein frequency and lean on FILAMENT plus a rich mask.
   
   

4. Deep conditioning mask - once per week for slip and friction control
   Choose a mask with fatty alcohols, cholesterol, compatible oils, and cuticle-friendly lipids. This lowers combing forces so the strengthening gains from FILAMENT are not wasted during detangling and styling.
   
   

5. Chelating cleanse - once every 2 to 4 weeks if water is hard or you swim
   Use a chelating shampoo with EDTA or similar. Follow with FILAMENT the same day or next wash so the fiber is supported after mineral removal.
   
   

6. Heat discipline - every time you style
   Apply a true heat protectant from roots to ends, keep the temperature as low as possible, do fewer passes, and let hair cool before brushing. One slow pass is better than three quick ones.
   
   

7. Micro-trim - every 8 to 12 weeks
   Split ends are not permanently repairable. Dusting a small amount prevents splits from traveling up the shaft and protects your strength gains.
   
   

Why FILAMENT is the Anchor Step

• Targeted reinforcement where hair is weakest - FILAMENT focuses strength in porous and thinned zones so breakage drops first where you see it most.
  
  

• Balance between cortex and cuticle - FILAMENT supports internal structure while improving glide, which is why detangling gets easier within the first few uses.
  
  

• Routine compatibility - FILAMENT plays well with a wide range of shampoos and masks. Use a reconstructor only when your wet stretch test says you need it, not by default.
  
  

• Consistency over novelty - Running FILAMENT once per week for four to six weeks produces more reliable strength gains than mixing multiple hero products on the same day.
  
  

Elasticity and Porosity Checks You Can Do at Home

• Wet stretch test - after a wash, take one clean shed strand and stretch gently. Slight give then return means you are balanced. Taffy-like stretch means add a light protein reconstructor this week. Instant snap with no give means keep protein light and stick with FILAMENT plus a rich mask.
  
  

• Porosity feel test - if hair dries very quickly and tangles easily, treat it as high porosity and keep the pre-shampoo buffer and weekly mask. If hair stays damp forever and feels coated, do a chelating reset, then use FILAMENT.
  
  

Heat and Handling Rules that Prevent New Damage

• Towel blot, do not rub - press water out with a soft towel and avoid aggressive friction that lifts cuticles.
  
  

• Detangle under running water - use a wide tooth comb with slip from conditioner or mask so strands glide apart.
  
  

• Style on lower heat - keep irons and dryers at the lowest setting that achieves the finish you need and avoid repeated passes on the same section.
  
  

• Rotate stress points - change part lines through the week and avoid tight elastics in the same spot to protect crown and nape.
  
  

Minimalist Starter Maps by Hair Type

• Fine hair - FILAMENT once weekly, lightweight conditioner on other days, heat protectant every style, protein reconstructor only when the wet stretch test is very stretchy.
  
  

• Medium hair - FILAMENT weekly, rich mask weekly, chelate every 3 to 4 weeks if water is hard, protein reconstructor every 3 weeks if elasticity calls for it.
  
  

• Coarse curls or relaxed textures - FILAMENT weekly, thin pre-shampoo oil each week to control water swell, creamy leave-in on non-wash days, reconstructor every 2 to 4 weeks only if needed by the stretch test.
  
  

Fast Answers for Real Problems

• Best way to strengthen hair fast after bleaching - run one FILAMENT session each week, keep heat honest, and use a rich mask for slip. Expect easier detangling in weeks two and three and bigger gains as trims remove old damage.
  
  

• How to strengthen weak brittle hair without heaviness - use FILAMENT weekly, choose lighter conditioners, and add a reconstructor only if the wet stretch test shows mushy behavior.
  
  

• How to fix breakage on the top of the head - lower dryer heat, avoid high tension with round brushes on soaking wet hair, target Filament to crown and ends, and rotate your part to spread stress.
  
  

• Do I stack FILAMENT with other hero treatments - run Filament as the single anchor on its day. If you want to test another hero later, use it on a different day and reassess after four to six weeks.
  
  

The 4-Week Checklist

Week 1

• Pre-shampoo buffer if porous.
  
  

• Filament session with even coverage.
  
  

• Heat protectant on any style.
  
  

• Log wet stretch test result.
  
  

Week 2

• Filament session midweek.
  
  

• Add mild reconstructor only if the stretch test is taffy-like.
  
  

• Rich mask once for slip.
  
  

• Heat protectant on any style.
  
  

Week 3

• Filament session.
  
  

• Rich mask twice if detangling still snags.
  
  

• No strong protein unless the stretch test requires it.
  
  

• Heat protectant on any style.
  
  

Week 4

• Filament session.
  
  

• Chelating reset if hair feels coated, then Filament in the same or next wash.
  
  

• Micro-trim a quarter inch to stop splits from creeping.
  
  

• Review your hair log and adjust only one lever at a time.
  
  

Run this sequence for one month, then keep FILAMENT weekly for months two and three. Keep heat in check, trim lightly, and use protein only when the wet stretch test tells you to. This is how stronger hair becomes the default rather than a good week followed by a setback.
