Coat 101: How to Repair Damaged Coat


Keeping your dog’s coat silky smooth and free from damage can be extremely hard. For long coated breeds like Shih Tzus and Yorkies, preventing damage is your #1 priority. Since it’s impossible to keep your dogs from playing and getting dirty, it’s also impossible to prevent damage. No worries though – it can be fixed!

Remember when we talked about the cortex? (If you don’t, check it out here.) When the cuticle layer gets damaged, or doesn’t get laid back down by conditioner, the cortex becomes open to damage – specifically loss of pigment or loss of proteins – causing frizz, split ends and broken coat.


Once the cortex is damaged, there’s only a couple things you can do.

  1.  Remove the damage. One of the simplest things to do is cut off the damage. However, when you want to keep coat length, this isn’t the best option for you.
  2.  Repair the damage. Add back lost pigment with our color shampoos (if needed) and restore lost proteins.


Assuming you don’t want to just cut the damaged parts off, your only option is to repair the damage as best you can, and protect the coat from further damage! It is vital to strengthen damaged hair that has been weakened from loss of proteins.


First things first – bathe your dog in your favorite Chris Christensen shampoo. Rinse thoroughly, and follow with a color treatment shampoo – White on White, Red on Red, Black on Black, Gold on Gold – if necessary.

Pro Tip: ALWAYS apply your color treatment shampoo BEFORE applying Thick N Thicker or Spectrum One Substance Builder! 


Thick N Thicker Volume Response repairs damage and creates volume by implanting proteins into the cortex. By replacing the lost proteins, Thick N Thicker Volume Response, strengthens weakened hair strands, and helps to repair split ends. Note: It may not repair all damage the first time. If the coat is severely damaged, or isn’t being protected from damage, it will take a couple applications, at least, to repair the damage. 


It is very important to NOT SKIP THIS STEP. You have to lock the proteins and color pigment into the hair shaft, by flattening the cuticle layer – this means conditioner! And in the case of damaged coat – lots of it!

In severe damage cases (breakage, thinning hair, etc.) seal in the proteins with Spectrum Ten Hypro Pac. Make sure to leave this on for at LEAST 5 minutes. If you have a long coated breed, you can also use this to wrap and leave it over night!

If the damage isn’t too severe, use your favorite Chris Christensen conditioner, or conditioner appropriate for your breed’s coat type. If you’re not sure, you really can’t go wrong with Day to Day Moisturizing Conditioner!



To prevent further damage, and maintain healthy coat, make sure to keep the coat strong, & healthy by spraying Precious Drop lightly over the coat before drying! (Precious Drop can be used on dry coat too!) Precious Drop contains Keratin (which is the protein that hair is made of!) to help keep the coat strong, while moisturizing, and taming frizz! On soft and drop coats, Precious Drop can be used daily. For rough/coarse coats, limit use to right after the bath, to prevent the coat from becoming too soft.


Even on healthy coat, we recommend you use Thick N Thicker Volume Response and White on White (also Black on Black, Red on Red, Gold on Gold) treatments every 2-3 baths to maintain coat health and to not over-do it. By skipping application every other or every two baths, the products work more effectively which gives you the best result!

    Question: What’s the difference between Thick & Thicker & Spectrum One Substance Builder?? In both application (when) & result? My pup’s coat is healthy, shiny – just in-between puppy & adult. He’s a 5 month PW Corgi & heading for shows this weekend. Thanks.

      Thick N Thicker works for all coat types, while Spectrum One Substance Builder is made specifically for rough and wire coat types. They both do the same thing, add volume and repair damage, and will give very similar results. 🙂

    I assume that the Thick N Thicker is washed out well, according to label instructions before applying the Hypro PAC. I have a beautiful Maltese but she has think silky hair. This repair protocol is the most amazing thing with her hair. Even before the Precious Drop came out, it works like magic for her.

    My cats white ruff is stained. He licks it. I keep a coffee filter on it most of the time. Can you help? What product would work to take the stain out. I wash him weekly. for shows.

      Pro-Gro and Coat Link Coat Dressing are great for moisturizing and sealing the cuticle! Precious Drop contains Keratin, which is a protein that makes up hair. Precious Drop helps maintain health and strengthens the hair!
